Function Composition in JavaScript! 🛠️

Function composition is a powerful technique to build clean, readable code by combining simple functions. Here’s a practical example:

1. Trim whitespace from a username
2. Convert the name to uppercase
3. Generate a greeting message
4. Check out this code snippet:

let username = "  Harley  ";
const trim = (name) => name.trim();
const convertToUpper = (name) => name.toUpperCase();
const generateMessage = (name) => `Hello ${name}, Good Morning!`;

const result = generateMessage(convertToUpper(trim(username))); // it goes right to left
console.log(result); // "Hello HARLEY, Good Morning!"

By composing these functions, you can transform data step-by-step in a clear and efficient manner. This approach is not only elegant but also helps in maintaining and scaling your code.
