Description:

This PR includes the following improvements:

  1. Refactoring the use of the in operator: Replaced the use of the in operator on an empty object {} with Object.prototype to properly check if parts[0] is a property of JavaScript's built-in objects. The previous approach always returned false, making the check ineffective.

  2. Optimization of null assignment logic: When isReserved is true, assigning null to parts[0] was unnecessary. Instead, parts[0] is now retained to avoid redundant null assignments and improve the overall logic.
