lib: Enhancing Performance and Readability with Switch Statements 🚀

Hi, this PR will result in a very minimal performance improvement by changing from multiple if conditions to a switch statement. Since a switch statement utilizes a branch table (correct me if I'm wrong), the gain in performance will be marginal, but it enhances code readability.

I've attached a picture of the JavaScript benchmark I ran, and there's a YouTube video demonstrating how a switch statement can lead to performance gains. The video showcases how the C compiler optimizes switch statements, and if I'm correct, this optimization principle should also apply to the V8 engine, which JIT compiles JavaScript to assembly language: YouTube link.
