Javascript code to remove falsy value like null, undefined, false from array

javascript Share on :

The code can be used to remove falsy values from an array using Javascript. Values like null, undefined, blank string, false are considered as falsy values.

const my_array = [10, false, null, "devsheet", undefined];
const filtered_array = my_array.filter(Boolean);
// -> [10,"devsheet"]

We are using Array.filter(Boolean) to filter out falsy values from the array. We have created an array my_array that contains the blank strings, false, null, and undefined items in it. It will filter all these values and return a new array in the filtered_array variable.

Another example to remove falsy values from array using Array.filter() method

const fruits = ["apple", false, "banana", null, undefined];
const filtered_fruits = fruits.filter(function (value) {
    return value ? true : false;
});
console.log(filtered_fruits);

We are given an array named fruits and we want to filter the falsy values from it. We are using Array.filter() method here and getting filtred array in filtered_fruits constant.
