🚀 𝐋𝐨𝐨𝐤𝐢𝐧𝐠 𝐭𝐨 𝐚𝐝𝐝 𝐬𝐨𝐦𝐞 𝐢𝐧𝐭𝐞𝐥𝐥𝐢𝐠𝐞𝐧𝐜𝐞 𝐭𝐨 𝐲𝐨𝐮𝐫 𝐟𝐫𝐨𝐧𝐭𝐞𝐧𝐝 𝐚𝐩𝐩? 🎨🤖

If you've ever struggled to choose the right text color for a dynamic background (we've all been there 🙋‍♂️), here’s a cool solution using Brain.js—a simple yet powerful JavaScript library for machine learning right in your browser!

I recently explored Brain.js to solve this very problem: automatically selecting black or white text based on any background color for better readability.

💡 𝐇𝐨𝐰 𝐝𝐨𝐞𝐬 𝐢𝐭 𝐰𝐨𝐫𝐤?

Train a neural network with sample background colors and the most suitable text color.

Input new background colors and let Brain.js predict which text color (black or white) offers the best contrast.

Implement this directly into your app to make text always readable, no matter the background!

Here’s an example prediction: For an orange-ish background color { r: 1, g: 0.4, b: 0 }, Brain.js tells me:

White Text: 99% confidence ✅

Black Text: 0.2% confidence ❌

Automatic Batching in React 18

Tanoy Basak — Wed, 16 Oct 2024 04:57:01 +0000

React 18 introduces automatic batching to optimize updates and improve performance. Batching is the process of grouping multiple state updates into a single re-render, reducing unnecessary renders and making updates more efficient.

In previous versions of React, batching was limited to event handlers (e.g., clicks, input changes), but in asynchronous code like setTimeout, Promise, or async functions, state updates were not batched automatically. React 18 expands this batching to cover more cases, including asynchronous code.

How Automatic Batching Works:
When multiple setState calls are made, React now automatically batches these updates together, whether they happen inside an event handler, a timeout, or any asynchronous function. This ensures that React re-renders only once, no matter how many state updates occur in between.

Key Benefits:

Performance: Reduces the number of renders when multiple state updates occur, making apps faster.
Cleaner Code: Developers no longer need to worry about manually batching updates in async code.

React Fiber

Tanoy Basak — Wed, 31 Jul 2024 15:47:10 +0000

Exploring React Fiber: Enhancing Performance and Responsiveness

React Fiber represents a complete overhaul of the React core algorithm, focusing on improving performance and responsiveness. Its primary objective is to enable incremental rendering, allowing React to divide rendering tasks into smaller chunks and pause or resume work as needed. This approach prioritizes updates, resulting in a smoother user experience, especially in large applications.

Key Features of React Fiber

Incremental Rendering: Fiber breaks down rendering tasks into smaller units, allowing React to yield control back to the browser when necessary, enhancing the application's responsiveness.
Concurrency: Fiber introduces the ability to manage multiple tasks concurrently, enabling efficient prioritization of updates and rendering management.
Error Boundaries: Fiber introduces Error Boundaries, a new error-handling mechanism that allows developers to catch errors in the component tree and display fallback UI.
Scheduling: Fiber's scheduling mechanism prioritizes and manages updates efficiently, ensuring high-priority updates are processed before lower-priority ones.

The Fiber Lifecycle

React Fiber introduces a new lifecycle for processing updates and rendering components, consisting of three main phases:

Render Phase: In this phase, React calculates the new component tree based on updates (e.g., new state or props). Also known as the "reconciliation phase," React can pause and resume work during this phase, yielding control back to the browser to maintain responsiveness.
Commit Phase: After the render phase, React enters the commit phase, where it applies the calculated changes to the DOM. Known as the "flush phase," this phase cannot be interrupted as it involves making actual changes to the DOM.
Cleanup Phase: Following the commit phase, React performs necessary cleanup, such as unmounting unneeded components and running side effects like componentDidUpdate or componentWillUnmount.

Understanding Fiber in Action

Consider an application with two components: Parent and Child. The Parent component includes a button that updates its state and triggers a re-render of both the Parent and Child components when clicked.

With React Fiber, when the button is clicked and the state is updated, React creates a work-in-progress tree based on the new state. It then calculates the necessary DOM updates and schedules them. Fiber's incremental rendering and prioritization mechanisms ensure that updates are processed efficiently without blocking the main thread.

React Fiber’s advanced capabilities significantly enhance performance and responsiveness, making it a powerful tool for developers building complex, dynamic applications.

Proxy Pattern

Tanoy Basak — Tue, 30 Jul 2024 14:13:18 +0000

Proxy is a structural design pattern that lets you provide a substitute or placeholder for another object. A proxy controls access to the original object, allowing you to perform something either before or after the request gets through to the original object.

Let’s create a person object, that represents John Doe.

Now lets analyze an interview question :

𝗛𝗼𝘄 𝗰𝗮𝗻 𝗶 𝘀𝘁𝗼𝗽 𝘀𝗼𝗺𝗲𝗼𝗻𝗲 𝘁𝗼 𝗰𝗵𝗮𝗻𝗴𝗲 𝘁𝗵𝗲 𝗶𝗱 𝗶𝗻 𝘁𝗵𝗲 𝘂𝘀𝗲𝗿 𝗼𝗯𝗷𝗲𝗰𝘁 ?

To freeze the id property in a JavaScript object using a Proxy, you can define a Proxy handler that prevents the id property from being modified. Here's how you can do it :

Composability

Tanoy Basak — Mon, 29 Jul 2024 05:30:50 +0000

Composability in JavaScript refers to the ability to combine smaller, reusable functions, components, or modules to build more complex and larger functionalities. It allows developers to write cleaner, more maintainable, and modular code.

In functional programming emphasizes composing functions to create more complex behaviors.

Key concepts include:

Higher-order functions: Functions that take other functions as arguments or return them.

Pure functions: Functions that have no side effects and return the same output given the same input.

Function composition: Combining two or more functions to produce a new function.

Working of CDN

Tanoy Basak — Sun, 28 Jul 2024 12:40:54 +0000

A CDN is a geographically distributed network of servers that work together to deliver content to end users with high availability and performance.

CDNs reduce latency by caching content closer to the end users.

When a user requests content from a website or application that utilizes a CDN, the request is redirected to the nearest CDN server instead of the origin server.

If the requested content is already cached on the CDN server, it is served directly from the cache, eliminating the need to retrieve it from the origin server. This reduces the distance the data has to travel and minimizes the response time.

Building Design Systems

Tanoy Basak — Thu, 25 Jul 2024 06:16:22 +0000

Building Design Systems

The design system is a collection of patterns and guidelines that are used to design and develop a digital product and that allows designers and developers to deliver consistent experiences, regardless of the device or technology used.
It is adopted by many companies as a design tool around which a product is built in its various components, sharing the language, the objectives and the procedures, ultimately creating its own identity for the product that is consistent with all the company’s communication channels.
Building design systems using Atomic Design pattern

Atomic design provides a clear methodology for crafting design systems. It is a mental model, and not a linear process, based on ‘’ do one thing and do it well ‘’, a scalable methodology, oriented towards problem solving and which favors usability.
Atomic design gives us the ability to traverse from abstract to concrete. Because of this, we can create systems that promote consistency and scalability while simultaneously showing things in their final context. And by assembling rather than deconstructing, we’re crafting a system right out of the gate instead of cherry-picking patterns after the fact.

Here’s a brief overview of the different levels in atomic design:

Atoms: These are the basic building blocks of the design system. Atoms include fundamental HTML elements such as buttons, inputs, labels, and more. They represent the smallest, indivisible parts of the user interface.
Molecules: Molecules are groups of atoms bonded together and act as a unit. For example, a form label, input, and button can combine to create a search form molecule. Molecules start to take on their own distinct properties and serve a particular function.
Organisms: Organisms are relatively complex components composed of groups of molecules and/or atoms. They form distinct sections of an interface, such as a navigation bar, a footer, or a card component. Organisms can consist of similar or different types of molecules.
Templates: Templates are page-level objects that place components into a layout and articulate the design’s underlying content structure. They are essentially a skeleton of the final page, containing placeholders for the actual content.
Pages: Pages are specific instances of templates that include real content. They provide a snapshot of the final user interface, showing how all the components come together to form a complete, working design.
