Question

http://jsfiddle.net/zzTsc/

I have a JSON that holds some values which get concatenated into a string but when I change the value of the JSON the string doesn’t take the name values. How can I make the string take the new values without re-declaring the same string?

See I could easily put string = name.first + "<br />"+name.last; right below where I change the JSON value but then when I wanna edit the format of that string I’ll have to change it twice.

That’s not how variables work. You have to set the value of string again for it to update.

Here’s an improved version so you don’t have to change it twice if you want to edit something:

function generateString(name) {
    return name.first + "<br />"+name.last;
}
var string = generateString(name);
