Arrow functions, also known as lambda expressions, are a concise syntax for writing JavaScript functions. They were introduced in ES6 (ECMAScript 2015) and have become increasingly popular due to their simplicity and expressiveness.
Arrow functions, also known as lambda expressions, are a concise syntax for writing JavaScript functions. They were introduced in ES6 (ECMAScript 2015) and have become increasingly popular due to their simplicity and expressiveness.
Arrow functions offer several advantages over traditional function declarations and expressions:
function add(a, b) {
return a + b;
}
const add = (a, b) => a + b;
The syntax of an arrow function is as follows:
(parameters) => { function body }
For example, the following arrow function returns the sum of two numbers:
const add = (a, b) => a + b;
If the function body consists of a single expression, the curly braces and the return
keyword can be omitted:
const add = (a, b) => a + b;
Arrow functions have a wide range of applications in JavaScript development, including:
