Question

I have an array ["Lorem", "", "ipsum"]. I would like to remove the empty string from this array and get ["Lorem", "ipsum"].

Is there any way to do this without using the loop and traversing through each element and removing it?

You may use filter :

var newArray = oldArray.filter(function(v){return v!==''});

The MDN has a workaround for IE8 compatibility. You might also use a good old loop if you’re not going to use filter anywhere else, there’s no problem with looping…
