Adding values to JavaScript Sets is fundamental for building dynamic collections of unique elements during runtime. With over 25 years of experience in software development and as the creator of CoreUI, I’ve used Set addition operations extensively in UI component state management and data processing. From my expertise, the most straightforward approach is using the add() method which automatically ensures uniqueness and maintains insertion order. This method provides efficient collection building while preventing duplicate entries.

Staging changes is a fundamental Git workflow step that allows you to selectively prepare files for commit and organize your modifications logically. As the creator of CoreUI, a widely used open-source UI library, I’ve staged thousands of changes across multiple repositories, carefully organizing commits for clear history and effective code reviews. From my expertise, the most essential approach is to use git add command with specific files or patterns. This method provides precise control over what changes are included in each commit, enabling atomic commits and better project organization.
