In Python stringValue was given as a string variable:

stringValue = '{"DATA":{"VERSION":1.1, "STATE":True, "STATUS":"ONLINE"}}'

I can go ahead and "convert" or "cast" it as Python dictionary using eval built in function:

result = eval(stringValue)

Is there a way to do the same in javascript if we would be given var stringValue as:

var stringValue = '{"DATA":{"VERSION":1.1, "STATE":true, "STATUS":"ONLINE"}}'

>Solution :

use eval

With one caveat … you’ll need to add ( and ) to the string

// this is the ORIGINAL value of the string in the question!!!
var stringValue = "{'DATA':{'VERSION':1.1, 'STATE':true, 'STATUS':'ONLINE'}}";
var result = eval(`(${stringValue})`);
console.log(result)

NOW that you changed the question

and make me look retarded – i.e. swapped ' and " – now you CAN use JSON.parse as a comment suggested

var stringValue = '{"DATA":{"VERSION":1.1, "STATE":true, "STATUS":"ONLINE"}}';
var result = JSON.parse(stringValue);
console.log(result);
