Remove empty elements from an array in Javascript

Question

How do I remove empty elements from an array in JavaScript?

Is there a straightforward way, or do I need to loop through it and remove them manually?

Answer 1

When using the highest voted answer above, first example, i was getting individual characters for string lengths greater than 1. Below is my solution for that problem.

var stringObject = ["", "some string yay", "", "", "Other string yay"];
stringObject = stringObject.filter(function(n){ return n.length > 0});

Instead of not returning if undefined, we return if length is greater than 0. Hope that helps somebody out there.

Returns

["some string yay", "Other string yay"]
