Add JavaScript ES6 Concepts Documentation

Issue Title: Add JavaScript ES6 Concepts Documentation

Is your feature request related to a problem? Please describe. The current issue is a lack of comprehensive documentation on JavaScript ES6 concepts within the repository. Contributors and newcomers to the project may struggle to understand and leverage modern JavaScript features due to this gap.

Describe the solution you'd like I would like to see the repository updated with thorough documentation on ES6 concepts, which should include explanations, code examples, and best practices for ES6 features like arrow functions, classes, destructuring, template literals, let and const, and more.

Describe alternatives you've considered I haven't considered any alternatives as adding ES6 documentation directly to the repository seems to be the most straightforward and inclusive solution.

Additional context

• The existing documentation in the repository.
• The significance of up-to-date JavaScript knowledge in web development.
• My commitment to maintaining the documentation and ensuring it stays current with future ES6 updates and new JavaScript features.
