#angular #javascript #webdev #programming

Learn Angular Binary Assignment Operators Visually
Struggling to understand binary assignment operators like +=, *=, ||=, or ??= in JavaScript or Angular? This interactive Angular demo makes it easy:

✅ Hands-On Learning – See how operators work in real-time, not just in theory.
✅ Built with Angular 20 – A lightweight, modern example to enhance your understanding.
✅ Visual Feedback – Modify values and instantly see the effects of each operator.
✅ Perfect for Beginners – Great for those new to JavaScript or Angular.

What Does the App Do?

Interactive Angular Demo: Binary Assignment Operators in Action

This app visually demonstrates key JavaScript/Angular binary assignment operators through real-time interaction.

Features:

🔹 Mathematical Operations
Increment (+=), Decrement (-=), Multiply (=) Square a number (*=)

🔹 Logical Operations
Set a message only if empty (||=)
Toggle/reset a flag only if true (&&=)

🔹 Nullish Coalescing (??=) Behavior
Assign a default value only if the variable is null or undefined

Project Overview:

The User Interface

The UI is clean and split into three sections:

- Count Operations

<div>
  <h2>Count: {{ count }}</h2>
  <button (click)="count += 1">Increment (+1)</button>
  <button (click)="count -= 1">Decrement (-1)</button>
  <button (click)="count *= multiplier">Multiply</button>
  <button (click)="count **= 2">Square</button>
</div>
Enter fullscreen mode Exit fullscreen mode

- Message Controls

<div>
  <h3>Message: {{ message }}</h3>
  <button (click)="message ||= 'Hello, Angular!'">Set Message if Empty</button>
  <button (click)="message &&= ''">Clear Message if Exists</button>
</div>
Enter fullscreen mode Exit fullscreen mode

- Boolean Logic

<div>
  <h3>Condition: {{ condition }}</h3>
  <button (click)="condition ??= true">Set if Undefined / Null</button>
  <button (click)="condition &&= false">Reset if True</button>
</div>
Enter fullscreen mode Exit fullscreen mode

How to Run the App:

- Step 1: Clone the Repo
