JavaScript - reverse words in a given string

In this article, we would like to show you how to reverse words in a given string in JavaScript.

Practical example

In the example below, we split the string into elements, reverse their order, and then we join them all together.

// ONLINE-RUNNER:browser;

function reverseString(string) {
    return string.split(' ').reverse().join(' ');
}

console.log( reverseString('Hello world'));             // world Hello
console.log( reverseString('Reverse words in string')); // string in words Reverse

Output:

world Hello
string in words Reverse
