How can I remove empty object in from an array in JS

Question

I have an array of objects and when I stringify, it looks like this:

"[[{"entrReqInv": "Neither"},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{},{}]]" 

How can I remove the empty {}s?

Answer 1

var newArray = array.filter(value => Object.keys(value).length !== 0); 

Answer 2

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; });
