Return multiple variables from a JavaScript function?

rated 0 times [ 168] [ 6] / answers: 1 / hits: 52680 / 12 Years ago, thu, april 19, 2012, 12:00:00

In python, to return multiple variables, I can do --

def function_one(i):

    return int(i), int(i) * 2



value, duble_value = function_one(1)

How would I achieve this same result using javascript if functions may only return a single return value? (I assume using an array?)

You need to either use an array or an object.

For example:

function test() {

    return {foo: bar, baz: bof};

}



function test2() {

    return [bar, bof];

}



var data = test();

foo = data.foo;

baz = data.baz;



data = test2();

foo = data[0];

baz = data[1];
