How to remove a specific element in array in JavaScript [duplicate]

Question

If I have array, for example:

a = ["a", "b", "c"] 

I need something like

a.remove("a"); 

How can I do this?

Answer 1

var newArray = []; var a=["a","b","c"]; for(var i=0;i<a.length;i++)     if(a[i]!=="a")          newArray.push(a[i]); 

As of newer versions of JavaScript:

var a = ["a","b","c"]; var newArray = a.filter(e => e !== "a"); 

Answer 2

remove = function(ary, elem) {     var i = ary.indexOf(elem);     if (i >= 0) ary.splice(i, 1);     return ary; } 

provided your target browser suppports array.indexOf, otherwise use the fallback code on that page.

If you need to remove all equal elements, use filter as Rocket suggested:

removeAll = function(ary, elem) {     return ary.filter(function(e) { return e != elem }); }
