Documentation: Javascript Function Implementation of Observer Pattern

[kattsky]

Hi @ash-teach

I've submitted another PR to provide a documentation for my PR #53

This documentation provides the following:

• an overview with diagram of the two key objects participating in the pattern
• key aspects of the Observer Pattern
• It's application in event-driven programming

Hello @kattsky,

Overall, the article provides a clear and detailed explanation of the Observer pattern in JavaScript, along with code examples and a diagram to illustrate the concepts. The only suggestions I would like to give are;

• Introduction Clarity: The introduction provides a clear overview of the Observer pattern and its relevance in JavaScript, which is great. Consider adding a brief example or scenario where the Observer pattern could be applied to make it more relatable to readers.
• If possible, please explain the diagram in brief to aid understanding.

Overall Great work, Katrina!

Thanks, @kattsky, this is great. Some formatting issues to fix, and one more strategic issue to address (which I think you can do most simply by removing the excess code i.e. as suggested in no. 1 in my final comment above).
