In this article, we would like to show you how to remove empty strings from an array in JavaScript.

Quick solution:

const outputArray = inputArray.filter(x => typeof x !== 'string' || x.length > 0);

 

Practical example

In this example, we use filter() method to create a copy of the letters array without empty strings.

// ONLINE-RUNNER:browser;

const letters = ['A','', "",,,, 'B', 'C', 0, 1, 2];
const result = letters.filter(x => typeof x !== 'string' || x.length > 0);

console.log(result);  // [A,B,C]
