Implement the optional reviver parameter in JSON.parse( text [, reviver] )

[HalidOdat]

Currently the JSON.parse( text[, reviver] ) method only supports the first parameter which takes in a String and converts into an Object.
But, there is an optional function argument that JSON.parse( text[, reviver] ) method takes. It prescribes how the value originally produced by parsing is transformed, before being returned.

Example:

JSON.parse('{"1": 1, "2": 2, "3": {"4": 4, "5": {"6": 6}}}', (key, value) => {
  console.log(key); // log the current property name, the last is "".
  return value;     // return the unchanged property value.
});

• MDN documentation
• ECMAScript reference

You can check the Array.prototype.every implementation to see how to deal with JavaScript callback functions.

I can take this. Btw, the link to Array.prototype.every is pointing to the wrong line number. It should be 491.

Sure! Go for it :)
