Add exhaustive list of Error subclasses

[meganindya]

Currently, there are several Error instances like TypeMismatchError, InvalidDataError, etc. which are thrown from across all units. List all and make Error subclasses for each unique behaviour.

In which file of code there are errors sir?

Here is what I have found

1. InvalidDataError
2. InvalidAccessError
3. ItemNotFound
4. InvalidOperationError
5. InvalidSymbolError
6. TresspassingAccess
7. TypeMismatchError
8. ItemNotFoundError
9. UndefinedError

We can easily create a subclass from the Error class and member a message inside those.

Let me know if you want me to work on it.

class CustomError extends Error {
  constructor(message: string) {
    super(message);
    this.name = this.constructor.name;
    Object.setPrototypeOf(this, new.target.prototype);
  }
}
