array join() method with a separator

Question

var arr= ['g','o','o','d'];
var arr2 = arr.join();

Arr2 will be "g,o,o,d". I would like to get "good". I know there are a million other ways to achieve this but was curious if there was a way with join.

Thanks

Sure - just pass an empty string:

var arr2 = arr.join('');
