*Quick JavaScript Cheatsheet* 🚀 *Variables* - `let x = 5;` (block-scoped) - `const y = 10;` (constant) - `var z = 15;` (function-scoped) *Data Types* - Number: `let num = 10;` - String: `let str = "hello";` - Boolean: `let isTrue = false;` - Array: `let arr = ;` - Object: `let obj = { name: "Amit", age: 25 };` *Functions* - Regular: `function greet() { return "Hi!"; }` - Arrow: `const add = (a, b) => a + b;` *Conditionals* - `if (x > 5) { ... } else { ... }` - Ternary: `let result = x > 5 ? "Yes" : "No";` *Loops* - For: `for (let i = 0; i < 5; i++) { ... }` - While: `while (x < 10) { ... }` - ForEach (array): `arr.forEach(item => console.log(item));` *DOM Manipulation* - Get element: `document.getElementById("myId")` - Change text: `element.textContent = "New Text";` - Add event: `element.addEventListener("click", myFunc);` *React ❤️ for more*
