JavaScript - check if string is empty

In this article, we would like to show you how to check if string is empty in JavaScript.

Quick solution:

// ONLINE-RUNNER:browser;

const myString = '';

if (myString === '') {
    console.log('myString is empty');
} else {
    console.log('myString is not empty');
}

Practical examples

In this example, we create a custom function that checks if the string is empty.

// ONLINE-RUNNER:browser;

const isEmpty = (string) => {
    return string ? false : true;
};

console.log( isEmpty('') );            // true
console.log( isEmpty('sample text') ); // false

Note:

This solution can be used to check if the string is null or undefined too.
