javascript object, access variable property name?

I am messing around with JS, learning a stuff and I am wondering about something…
Say you have a function aFunc(), and you accept a string aFunc(val). The value is user defined and is then used to modify the CSS of an element.

For Example:

function aFunc(val){
    document.getElementById('something').style.val = 'red';
}

Say the user entered borderColor, it would somehow refrence borderColor where val is. I do not know how or if this is possible.

EDIT:
Please no eval() 🙂

Just use this as a base: JSBIN- Demo on a Div

var type = prompt("style");
var value = prompt("value");
document.body.style[type] = value;
