Is there a way to use variable keys in a JavaScript object literal?

Question

I have code like this.

var key = \"anything\";   
var object = {   
    key: \"key attribute\"  
};

I want to know if there is a way to rep

Answer 1

On modern Javascript (ECMAScript 6) you can sorround the variable with square brackets:

var key = "anything";

var json = {
    [key]: "key attribute"
};
