JavaScript is a cornerstone of modern web development, enabling interactive and dynamic features in websites. Whether you're building front-end applications or back-end services with Node.js, understanding JavaScript is essential. Let's dive into the basics and explore key concepts!

📌 Core Concepts

  • Variables & Data Types: Use let, const, or var to declare variables. Common types include string, number, boolean, array, and object.

  • Operators: Arithmetic (+, -, *, /), comparison (==, >, <), and logical (&&, ||, !) operators form the backbone of logic.

  • Control Structures: Master if/else, switch, for, while, and do/while loops for flow management.

🧠 Functions & Objects

  • Functions: Define reusable blocks of code with function keywords.

🌐 DOM Manipulation

JavaScript interacts with HTML through the Document Object Model (DOM). Learn to select elements, modify content, and handle events.

🔁 Asynchronous Programming

  • Callbacks: Traditional approach for handling async operations.
  • Promises: Use .then() and .catch() for better error handling.
  • Async/Await: Modern syntax simplifying async code.

✅ Best Practices

  • Keep code concise with arrow functions =>.
  • Use strict mode for error detection: 
    'use strict';
  • Modularize projects with ES6 modules (import/export).
