Arrow functions are a modern and shorter way to write functions in JavaScript. They were introduced in ES6 to make code cleaner and easier to read.
Instead of using the function keyword, arrow functions use the => symbol. This helps developers write faster and more readable code, especially in small functions.
Arrow functions are widely used in modern JavaScript projects, frameworks, and libraries.
Why Use Arrow Functions
- They make code shorter and cleaner
- They are easier to read
- They reduce unnecessary syntax
- They are commonly used in modern JavaScript
- They work well with callbacks and events
Arrow functions help developers write efficient and professional code.
This is a regular function that adds two numbers and returns the result. It works perfectly but uses more syntax.
Here, the same function is written using arrow syntax. It performs the same task but with less code.
This makes the function easier to read and maintain.
This example shows how arrow functions can be written in a single line when the function has only one expression.
By mastering arrow functions, students gain modern JavaScript skills and move closer to writing professional, industry-ready code.
