Contribution: Sharing Problem Statements & Solutions for Design Patterns in JS

[PrasanthVijayy]

Hi @ashishps1 !

I’ve been working on Design Patterns in JavaScript and shared a easy understanding of how they work. I’d like to share some problem statements along with solutions related to these patterns.

Could you let me know if you're open to adding this to your repo? If so, please let me know which folder I should create the PR for.

Thanks in advance!
