To capitalize the first letter of a string in JavaScript, you can use this simple function:

✅ Example:

📌 How it works:

• str.charAt(0).toUpperCase() → Capitalizes the first character.

• str.slice(1) → Gets the rest of the string starting from the second character.

• The two parts are concatenated.

To capitalize the first letter of each word in a string

✅ Example:

console.log(capitalizeEachWord(“hello world”));
// Output: “Hello World”

console.log(capitalizeEachWord(“javaScript is awesome”));
// Output: “Javascript Is Awesome”

🔍 How it works:

• split(' ') → Splits the string into an array of words.

• map(...) → Capitalizes the first letter of each word.

• join(' ') → Joins the capitalized words back into a single string.
