implement JSON.parse()

Question

This is a follow-up on 21. implement JSON.stringify().

Believe you are already familiar with JSON.parse(), could you implement your own version?

In case you are not sure about the spec, MDN here might help.

JSON.parse() support a second parameter reviver, you can ignore that.

note

Don't use JSON.parse() in your code here It doesn't help you practicing your skills.

Code

/**
 * @param {string} str
 * @return {object | Array | string | number | boolean | null}
 */
function parse(str) {
  // your code here
}
