Try to implement a JSON Parser in JS at https://algodaily.com/challenges/implement-json-parse
---
In JavaScript by default, there is a method that can parse a given JSON string, and it can be invoked by calling `JSON.parse()`. The way this method works is constructing the JavaScript value or object described by the string.
Can you implement your own version of this method, called `parseJSON`, accepting one parameter (the JSON string), keeping in mind all the value types and restrictions in the JSON format?
```js
function parseJSON(input) {
// fill in this method
}
```
Your task is to create a function called `parseJSON` that takes a string as input and returns the corresponding JavaScript object. The function should be able to handle JSON-like strings, which can be:
- Primitive types: `null`, `true`, `false`
- Strings wrapped in quotes: `"string"`
- Arrays: `[1, "a", null]`
- Objects: `{"key": "value", "anotherKey": 42}`
Your parser should return the corresponding JavaScript types for these string inputs. For example, if the input string is `"null"`, your function should return `null`.
