javascript-lodashHow do I use Lodash to remove empty objects from an array in JavaScript?
Using Lodash, you can remove empty objects from an array in JavaScript using the _.compact()
method. This method creates a new array with all falsey values removed. Falsey values include null
, undefined
, ''
, false
, 0
, and NaN
.
For example:
const array = [{}, {name: 'John'}, {}, {name: 'Mary'}, {}, null, 0];
const compactArray = _.compact(array);
console.log(compactArray);
// Output: [{name: 'John'}, {name: 'Mary'}]
The _.compact()
method takes an array as an argument and returns a new array with all falsey values removed. In this example, the falsey values include the empty objects and null
, 0
, which are all removed from the array.
