What is the best way to transform a string resembling JSON or a JS object into a valid JS object?

The specific String in question was originally part of a JavaScript object as shown below:

var nameVal = "Jacob";
var favNumbersVal =  "{\"firstNum\":0, \"secondNum\":1, \"thirdNum\":2}";

var aJSObject = {
    "name" = nameVal,
    "favNumbers" = favNumbersVal
};

I am particularly interested in the variable favNumbersVal. It is important to note that the quotation marks surrounding the value of favNumbersVal are standard double quotes used when defining a string.

The structure of the value in favNumbersVal is generated by a library dynamically.

My query is how can I convert the content of favNumbersVal into a JavaScript object, so that when I eventually transform sJSObject into JSON using JSON.stringify(), the value of aJSObject will be a JSON object with the value of favNumbers nested within it.

Answer №1

One way to parse JSON data in JavaScript is by using the JSON.parse() method:

var favNumbersVal =  "{\"firstNum\":0, \"secondNum\":1, \"thirdNum\":2}";
console.log(JSON.parse(favNumbersVal));
