Modern JavaScript Features

JavaScript has evolved significantly over the years. ES6 and later versions introduced many powerful features that make the language more expressive and easier to work with.

Arrow Functions

Arrow functions provide a concise syntax for writing function expressions:

const add = (a, b) => a + b;

Destructuring

Extract values from arrays and objects into distinct variables:

const { name, age } = person;
const [first, second] = array;

Async/Await

Write asynchronous code that looks synchronous:

async function fetchData() {
  const response = await fetch('/api/data');
  const data = await response.json();
  return data;
}

Template Literals

String interpolation and multi-line strings:

const greeting = `Hello, ${name}!
Welcome to the platform.`;

Conclusion

These features make JavaScript more powerful and developer-friendly. Staying up to date with modern JavaScript is essential for any web developer.
