How can I remove empty object in from an array in JS
You can use Array.prototype.filter to remove the empty objects before stringifying.
JSON.stringify(array.filter(function(el) { // keep element if it's not an object, or if it's a non-empty object return typeof el != "object" || Array.isArray(el) || Object.keys(el).length > 0;});
I would recommend using the following code:
var newArray = array.filter(value => JSON.stringify(value) !== '{}');I did not use Object.keys(value).length !== 0 because it not only removes empty objects { } but also removes empty arrays [ ]. If you only want to remove empty objects, use the above method.
