--description--

Arrow functions are a more modern way to write functions in JavaScript. They provide a more compact syntax compared to traditional function expressions. Arrow functions are defined using the => syntax.

const add = (a, b) => {
  return a + b;
}

In the example above, the arrow function add takes two parameters a and b and returns their sum. The return keyword is used to return the result of the addition operation.

If the arrow function has only one expression, the curly braces {} and the return keyword can be omitted. The expression will be implicitly returned.

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

In the example above, the arrow function add takes two parameters a and b and returns their sum. The return keyword and curly braces {} are omitted, and the result of the addition operation is implicitly returned.
