Unlock the Power of Custom Functions in JavaScript 🔓💡

🚀 Mastering Custom Functions in JavaScript

Custom functions help you write clean, reusable code that solves problems in a smarter way. Whether you're building a frontend UI or backend logic, defining your own functions gives you power and flexibility.

🧠 Why Use Custom Functions?

• Reduces code duplication
• Improves readability and modularity
• Makes debugging easier
• Reusable across multiple components or files

💡 Example: Capitalize Every Word

function capitalizeWords(str) {
  return str.replace(/\b\w/g, char => char.toUpperCase());
}

const title = "custom functions in javascript";
console.log(capitalizeWords(title)); // "Custom Functions In Javascript"

You can use this type of function in your frontend form handlers, blog formatting, or even in APIs!

✨ Pro Tip: Keep your functions short and focused on a single task!
