🧐 What is a String?

A string is a sequence of characters enclosed in:

✔ Double quotes → "Hello, World!"

✔ Single quotes → 'JavaScript is fun!'

✔ Backticks ( ) for Template Literals → I am learning JavaScript!

Strings are immutable, meaning once created, they cannot be changed. However, you can manipulate them using various methods.

🚀 String Methods You Must Know!

✅ 1. Accessing Characters in a String

You can access individual characters using indexing ([]) or .at().

let str = "JavaScript";
console.log(str[0]);     // Output: J
console.log(str.at(-1)); // Output: t (last character)

✅ 2. .length - Get String Length

Returns the number of characters in a string.

let text = "Hello, World!";
console.log(text.length);  // Output: 13

✅ 3. .charAt(index) - Get Character at Index
