Get property of object in JavaScript

If I have the following:

var test ='bar';

var sections = {
    foo: 'value1',
    bar: 'value2',
    baz: 'value3'
};

I can use sections.foo to output ‘value1’. Thats fine. However what if I want to get the value from sections according to another variable. Although this doesnt work what I mean is something like:

sections.test

Where test is the variable declared earlier, so the value returned would be ‘bar’.

I dont work a awful lot with js so any help would be appreciated 🙂 .. or if im approaching this the wrong way, feel free to say.

thanks

–>EDIT

The reason I wanted to do this is because the variable ‘test’ will be coming from the url and then I just wanted to load up further information depending on what page the user was on. 🙂

Use [] instead of ..

sections[test] // value2
