Convert an array into a separate argument strings

Question

How would I get this array to be passed in as a set of strings to the function? This code doesn't work, but I think it illustrates what I'm trying to do.

var strings = ['one','two','three'];  someFunction(strings.join("','")); // someFunction('one','two','three'); 

Thanks!

ES6

For ES6 JavaScript you can use the special destructuring operator :

var strings = ['one', 'two', 'three']; someFunction(...strings); 

ES5 and olders

Use apply().

var strings = ['one','two','three'];  someFunction.apply(null, strings); // someFunction('one','two','three'); 

If your function cares about object scope, pass what you'd want this to be set to as the first argument instead of null.
