Hoisting in JavaScript | Episode 3

Himanshu Gupta — Mon, 12 Jan 2026 06:08:27 +0000

🔍 What is Hoisting?

Hoisting is a JavaScript mechanism where variable and function declarations are moved to the top of their scope during the memory creation phase of the execution context.

⚠️ Only declarations are hoisted, not initializations.

🧠 How Hoisting Works

JavaScript code runs in two phases:
Memory Creation Phase
Code Execution Phase
During the memory creation phase:
Variables declared using var are initialized with undefined
Function declarations are stored in memory as they are
This allows:
Variables to be accessed before assignment
Functions to be called before declaration
Accessing a variable before assigning a value returns undefined
Accessing a variable that is not declared at all throws a ReferenceError

Variable declarations → undefined Function declarations → fully available

📌 Hoisting Behavior Summary
| Declaration Type | Hoisted | Initial Value |
| -------------------- | ---------- | ------------- |
| var variable | ✅ Yes | undefined |
| Function declaration | ✅ Yes | Full function |
| Function expression | ⚠️ Partial | undefined |
| Arrow function | ⚠️ Partial | undefined |
| Undeclared variable | ❌ No | Error |

✅ Example 1: Variable & Function Hoisting
`getName(); // Namaste Javascript
console.log(x); // undefined

var x = 7;

function getName() {
console.log("Namaste Javascript");
}`

Explanation

getName() is fully hoisted and can be called before declaration
x is hoisted and initialized with undefined
No error occurs

❌ Example 2: Accessing an Undeclared Variable
`getName(); // Namaste JavaScript
console.log(x); // ReferenceError: x is not defined
console.log(getName); // function getName() {...}

function getName() {
console.log("Namaste JavaScript");
}
`

Explanation

x is never declared
JavaScript throws a ReferenceError
Function declarations are still hoisted correctly

❌ Example 3: Function Expression Hoisting

`getName(); // TypeError: getName is not a function
console.log(getName); // undefined

var getName = function () {
console.log("Namaste JavaScript");
};
`

Explanation

-Function expressions behave like variables
-getName is hoisted as undefined
-Calling it as a function throws a TypeError

Interpreter vs Compiler: What’s the Difference?

Himanshu Gupta — Sun, 04 Jan 2026 16:00:18 +0000

🧠 Interpreter vs Compiler – What’s the Difference?

When we write code, the computer does not understand it directly.

Computers only understand machine language (0s and 1s).

So, programming languages use translators to convert human-readable code into machine-readable code.

There are two main types of translators:

Interpreter
Compiler

Let’s understand both in a very simple way 👇

🔍 What is an Interpreter?

An interpreter reads and executes code line by line.

How it works:

Reads one line of code
Converts it to machine language
Executes it
Moves to the next line

If an error occurs, the program stops immediately.

::contentReference[oaicite:0]{index=0}

✅ Key Points of Interpreter

Executes code line by line
Slower execution
Stops at the first error
No executable file is created

🧑‍💻 Languages That Use Interpreter

JavaScript
Python
PHP
Ruby

Example (JavaScript):


js
console.log("Hello");
console.log(a); // error
console.log("World"); // this will not run

Converting a Monolithic App to Microservice-Based Architecture

Himanshu Gupta — Sun, 14 Dec 2025 09:55:57 +0000

Summary: Converting a Monolithic App to Microservice-Based Architecture

This Blog focuses on the challenges and practical approach to converting a monolithic application into a microservice-based architecture, especially from the perspective of scalability, security, and efficient client consumption. The presenter uses Instagram as a real-world example to explain the concepts clearly.

Core Concepts and Challenges

Monolithic App Issues:
- Difficult to scale individual modules (e.g., Likes, Comments).
- Increasing server and database resources for one feature impacts the entire app and increases cost unnecessarily.
- Large teams face dependency conflicts, risking downtime if one component fails.
Naïve Microservice Approach:
- Simply splitting models (e.g., Authentication, Posts, Comments) into separate microservices and deploying them on different servers is not sufficient.
- The real challenge lies in:
- Ensuring security of each microservice.
- Implementing rate limiting to prevent abuse.
- Managing inter-service communication.
- Handling client consumption efficiently without exposing internal services.

Practical Implementation Steps

Division of Services:
- Split the monolithic app into smaller services (Auth, Users, Posts, Comments, Likes, Notifications).
- Each microservice may even use different types of databases based on needs (e.g., Redis for Auth, NoSQL for Posts).
Client Consumption Problem:
- Clients (mobile or web apps) require aggregated data from multiple services (e.g., user info, posts, comments).
- Hitting each microservice individually from the client is inefficient and insecure.
- Rate limiting and authentication become difficult when multiple endpoints are exposed.
API Gateway as a Central Entry Point:
- Introduce an API Gateway that acts as the single public endpoint.
- Clients only know and access the API Gateway, not individual microservices.
- The gateway routes requests internally to the right microservice based on URL paths or request type.
- All rate limiting, authentication, and security checks are implemented here.
Token-Based Authentication:
- Use JWT tokens to authenticate users.
- When a user logs in, the auth service issues a token.
- The API Gateway verifies this token on every request.
- After verification, the gateway injects user details (e.g., user ID) as headers before forwarding requests to microservices.
- This avoids each microservice needing to verify tokens independently.
Security Measures:
- Use asymmetric encryption (RSA algorithm) for JWT token signing:
- Private key used to sign tokens.
- Public key shared to verify tokens, enhancing security.
- Microservices accept requests only from the API Gateway (inbound network rules).
- Prevent direct access to microservices from outside sources.

Technology Choices (Not Prescriptive)

API Gateway can be provided by cloud platforms (AWS, etc.) or custom-built.
Backend server implementations can use Node.js, Go, Rust, or any preferred language based on team expertise and performance needs.
The presenter prefers Fastify on Node.js for speed but acknowledges alternatives.

Summary Table: Key Components and Their Roles

Component	Role/Function
Monolithic App	Single large app where all features are tightly coupled
Microservices	Small, independent services (Auth, Posts, Comments, Likes) with own databases
API Gateway	Single public endpoint that routes, authenticates, rate-limits, and aggregates microservice calls
JWT Tokens	Used for authenticating users and passing user info securely
RSA Algorithm	Used for signing/verifying tokens with private/public key pair
Security Rules	Restrict microservice access to only API Gateway; prevent direct external hits

Key Insights

Simply splitting a monolithic app into microservices is not enough; the architecture must ensure security, scalability, and efficient client interaction.
An API Gateway is essential to hide internal microservices and manage requests, authentication, and rate limiting centrally.
JWT with RSA encryption provides secure, scalable authentication across microservices without sharing secret keys.
Network-level security (inbound/outbound rules) is critical to restrict access among services and prevent unauthorized use.
This architecture improves scalability (e.g., scale only “likes” service if needed), reduces costs, and allows larger teams to work independently without causing system-wide failures.

Conclusion

The Blog offers a practical and structured approach to microservice migration from a monolithic app using real-world examples and best practices. It highlights security, efficient client consumption, and scalability as core pillars of modern microservice architecture. The presenter encourages feedback and further discussion on the topic.

How JavaScript Code is executed | Episode 2

Himanshu Gupta — Fri, 12 Dec 2025 07:20:04 +0000

When JavaScript runs your code, it doesn’t just start reading from the top and go all the way down.
It actually creates something called an Execution Context, which is like a special environment where your code lives and runs.

There are two types of execution contexts:

Global Execution Context (GEC) — created when the program starts.

Function Execution Context (FEC) — created each time a function is called.

Each execution context has two phases:
🧠 1. Memory Creation Phase (Creation Phase)

Before JavaScript executes your code, it scans the file and stores all variables and functions in memory.

Variables are set to undefined.

Functions are stored as they are (actual function code).

Think of it like setting up chairs before guests arrive at a party — everything is prepared for later use.

▶️ 2. Code Execution Phase

Now JavaScript executes code line by line.
Variables get their actual values.
Functions run when they are called.
Every time a function runs, a new execution context is created.
After a function finishes running:
It returns control to where it was called.
Its execution context is deleted.

📚 How the Call Stack Works

JavaScript uses a call stack to manage all running execution contexts.

The top of the stack is always the code being executed right now.
The bottom is always the Global Execution Context.
Whenever a function is called:
A new Function Execution Context is created.
It is pushed onto the stack.
When the function finishes:
Its context is popped off the stack.

🧩 Real-Life Example: Making a Sandwich 🥪

Imagine you’re making a sandwich.
Global Context = Your Kitchen
This is the main environment where everything starts.
Function Context = Each Task

Every time you perform a task (like cutting veggies or spreading butter), you temporarily focus on that task.

🧪 JavaScript Example

`var bread = "Brown Bread";

function makeSandwich() {
console.log("Start making sandwich");

function addButter() {
console.log("Adding butter");
}

addButter();
console.log("Sandwich is ready");
}

makeSandwich();`

🔍 What Happens Step-by-Step?

Global Memory Creation Phase

JavaScript sets up memory:

bread → undefined makeSandwich → function

Global Code Execution

bread = "Brown Bread"

makeSandwich() is called → a new Function Execution Context is created.

🍞 Inside makeSandwich() Execution Context
Memory Phase
addButter → function

Execution Phase

Print: "Start making sandwich"
Call addButter() → new execution context!

🧈 Inside addButter() Execution Context
Memory Phase

(no variables declared)
Execution Phase
Print: "Adding butter"
Execution context ends → popped off the stack
Back to makeSandwich()
Print: "Sandwich is ready"

Execution context ends → popped off the stack

Back to Global Context
After all code is done:
Global Execution Context is removed. Program finishes.

🎉 Final Thoughts

Execution Context and Call Stack may sound complicated, but they simply describe how JavaScript prepares and runs your code.

If you remember:

Memory Phase → setting things up
Execution Phase → running the code
Call Stack → managing what runs when
…you’ll understand how JavaScript actually works behind the scenes!

How JavaScript Works & Execution Context | EP-01

Himanshu Gupta — Fri, 12 Dec 2025 06:45:42 +0000

🧠 What Is Execution Context? (Simple Words)

Think of the execution context like a classroom where JavaScript works.

In this classroom:

There is a whiteboard where all important notes (variables & functions) are written → Memory Component

There is a teacher who reads and executes each instruction one-by-one → Thread of Execution

📌 1. Memory Component (Variable Environment)
🧠 Simple Meaning:

A place where JavaScript stores data before running the code.

🎒 Real-Life Example:

Imagine you enter a classroom and the teacher writes names on the board:

studentName = "Ali"

age = 10

greet = function(){...}

The whiteboard is the memory component, storing data before the lesson starts.

📌 2. Code Component (Thread of Execution)
🧠 Simple Meaning:

The part where JavaScript executes code line by line, like a teacher reading instructions one after another.

🎒 Real-Life Example:

After writing on the whiteboard (memory),
the teacher starts reading the notebook:

Say hello to the students

Explain the lesson

Ask a question

Wait for an answer

Move to next instruction

The teacher cannot read two lines at the same time.

That is the thread of execution.

📌 3. JavaScript Is Synchronous & Single-Threaded
🧠 Simple Meaning:

JavaScript does ONE thing at a time and in order.

🎒 Real-Life Example:

Imagine a student reading a book aloud.

They must finish one sentence before starting the next.

They cannot read two sentences at the same time.

That’s how JavaScript works—step-by-step, one-by-one.

💡 Full Real-Life Example Putting It All Together
`Code:
var name = "Sara";
function sayHi() {
console.log("Hi " + name);
}

sayHi();`

🧠 Real-Life Breakdown:

Memory Component (Whiteboard)

name: "Sara"

sayHi: function

Thread of Execution (Teacher reading steps)

Goes to sayHi()

Executes it → prints "Hi Sara"

JavaScript finishes this before moving to the next line.

🗂️ Scalable Folder Structure for Node.js + Express.js Projects (2025 Edition)

Himanshu Gupta — Wed, 06 Aug 2025 13:11:05 +0000

📦 Why Project Structure Matters
As your Node.js app grows, a good folder structure keeps your sanity intact. It makes your app:

Easier to scale

Easier to test

Easier to onboard new devs

Forget monolithic files. Let’s modularize smartly.

📁 Recommended Structure

my-app/
├── src/
│ ├── config/ # App configuration (env, DB, etc.)
│ ├── modules/ # Feature-based modules (User, Auth, etc.)
│ │ └── user/
│ │ ├── user.controller.ts
│ │ ├── user.service.ts
│ │ ├── user.model.ts
│ │ ├── user.routes.ts
│ │ └── user.validators.ts
│ ├── middleware/ # Custom middlewares
│ ├── utils/ # Utility functions/helpers
│ ├── jobs/ # Cron jobs, background workers
│ ├── app.ts # Express app setup
│ └── server.ts # Entry point
├── tests/ # Unit and integration tests
├── .env
├── .env.example
├── tsconfig.json # TypeScript config (if using TS)
├── package.json
└── README.md
🔍 Breakdown
src/modules/ — 💡 Feature First
Split features into self-contained modules:

Easier to test and scale

Encourages separation of concerns

Think DDD-lite (Domain Driven Design)

For example:

modules/
└── auth/
├── auth.controller.ts
├── auth.service.ts
├── auth.routes.ts
├── auth.model.ts
└── auth.validators.ts
src/config/ — 🔧 Config Central
Centralized configuration logic:

// config/database.ts
import mongoose from 'mongoose';
export const connectDB = async () => {
await mongoose.connect(process.env.MONGO_URI!);
};
src/middleware/ — 🔒 Middlewares
Store custom Express middleware here:

Error handlers

Auth guards

Rate limiters

Logging middleware (e.g., Morgan)

src/utils/ — 🧰 Shared Helpers
For things like:

Response formatters

Token generation

Password hashing

🧪 tests/ — Testing-First
Organize unit and integration tests per module:

pgsql

tests/
└── user/
├── user.controller.test.ts
└── user.service.test.ts
Use tools like:

Jest or Vitest (unit tests)

Supertest (API tests)

✅ Bonus Tips
Add src/types/ if you need global types.

Use a .env.example for teammates to know required environment variables.

Lint + Format using eslint and prettier.

Use module-alias to avoid ugly ../../ imports.

Use a layered structure only when needed — don’t over-engineer a todo app.

🚀 TL;DR
Use this structure if:
✅ You're building a mid-to-large scale API
✅ You want clean, modular code
✅ You care about testing and future scaling

ORM vs ODM: What's the Difference and When to Use Them?

Himanshu Gupta — Tue, 13 May 2025 09:39:22 +0000

If you're building applications that interact with databases, you've likely heard of ORM (Object-Relational Mapping) and ODM (Object-Document Mapping). These two concepts serve similar purposes—abstracting database access—but are designed for very different types of databases. Let’s break them down and explore when you should use each.

What is ORM?
ORM stands for Object-Relational Mapping. It’s a technique used to interact with relational databases like PostgreSQL, MySQL, and SQLite using the object-oriented paradigm of your programming language.

Instead of writing raw SQL, ORMs let you interact with your database using classes and objects.

What is ODM?
ODM stands for Object-Document Mapping. It’s used for document databases like MongoDB. These databases store data in formats like JSON or BSON, which naturally map to objects in many programming languages.

Your data has clear structure and relationships.

You need ACID transactions and complex joins.

Your app depends on SQL databases (e.g., for reporting).

Use ODM when:
Your data is hierarchical or semi-structured.

You prioritize flexibility and rapid iteration.

You’re using a NoSQL store like MongoDB.

What Are Standalone Components Angular 17 ?

Himanshu Gupta — Tue, 23 Apr 2024 10:57:09 +0000

Standalone Components in Angular 17 are a new addition to the Angular framework that provides developers with a way to create reusable, encapsulated components that can be easily shared across multiple Angular applications. These components are designed to be self-contained, meaning they have their own dependencies, styles, and functionality, making them independent of the application they are used in.

Unlike traditional Angular components that are tightly coupled with the application they belong to, Standalone Components can exist and function independently, making them highly versatile and portable. This independence allows developers to create components that can be used across different projects or even shared with the broader Angular community.

Benefits of Standalone Components

Reusability: Standalone Components promote code reuse by encapsulating functionality into self-contained units. Once created, these components can be easily reused across different projects, reducing duplication of code and development time.

Portability: Since Standalone Components are independent of any specific Angular application, they can be easily shared and distributed. Developers can package these components as libraries and distribute them via package managers like npm, allowing other developers to leverage their functionality in their projects.

Simplified Maintenance: By encapsulating functionality into standalone units, developers can better manage and maintain their codebase. Changes or updates to a standalone component only need to be made once, and those changes will reflect across all applications that use the component, streamlining the maintenance process.

Improved Collaboration: Standalone Components encourage collaboration among developers by providing a standardized way to create and share reusable UI elements. Teams can work together to create a library of shared components that can be used across multiple projects, fostering consistency and efficiency.

Enhanced Testing: Since Standalone Components are self-contained, they can be easily tested in isolation, allowing for more focused and efficient testing strategies. This makes it easier to identify and fix bugs, ensuring the reliability and stability of the components.

How to Create Standalone Components in Angular 17

Creating Standalone Components in Angular 17 is straightforward and follows the same principles as creating traditional Angular components. Developers can use Angular CLI or manually create components using Angular's component decorator.

To create a standalone component using Angular CLI:

ng generate component <component-name> --standalone

import { Component } from '@angular/core';
import {CommonModule} from '@angular/common';
@Component({
  selector: 'app-my-standalone-component',
  standalone: true,
  imports: [CommonModule],
  template: '<h1>Hello, World!</h1>'
})
export class MyStandaloneComponent {}

This command generates a standalone component with its own module, allowing it to be used independently of any specific Angular application.
