Return two variables in one function [duplicate]

Answer 1

The comma operator evaluates each operand and then returns the value of the last one.

You'd need to either return an array:

return [h, w];

...or an object:

return { h : h, w : w };

Which you'd then use as:

var test = test();
alert(test[0]); // "hello" - in the case of the array version

...or:

var test = test();
alert(test.w); // "world" in the case of the object version
