SYSTEM INTEGRATION & ARCHITECTURE 2 REVIEWER Advantages:  Provides a cleaner and more modern AJAX interface using Promises, leading to more readable and maintainable code.

Repositories - a central place where all the files for a project are stored. - Each repository can hold multiple files and folders, and it tracks the history of every change made. - Repositories can be public (accessible to everyone) or private (restricted access). Branches - crucial feature in GitHub that enable parallel development. You can create a branch to work on a new feature or fix a bug without a ecting the main codebase. Pull Requests - way to propose changes to a repository. When you submit a pull request, you’re asking the project maintainers to review and merge your changes into the main codebase. Markdown Basics: A Comprehensive Guide c. Nested Lists- Combine ordered and unordered lists. Markdown is a lightweight markup language that lets Format: you create formatted text using a simple syntax. It’s 1.
