Question

I have a working JavaScript code below which dynamically creates JSON object using JSON.parse method. Is there a shorter way to do this?

var a = '"hi"'; 
var obj = '{' + a + ':' + '"abc"' + '}';
console.log(JSON.parse(obj)); // outputs: OBJECT: {"hi":"abc"} 

something simplier like…

var a='hi';
console.log({a:"abc"}); // but outputs: OBJECT: {a:"abc"}

Answer 1

You can use square brackets to access a property whose name you have as a string:

var a = "hi";
var obj = {}; //obj is an object literal
obj[a] = "abc"; //Set the 'hi' property of obj

Note that JSON is just a data format. It is not JavaScript. You want a JavaScript object literal, not JSON.
