🔍 STL Lens

Learn and understand C++ STL — without leaving your editor.

STL Lens is a Visual Studio Code extension that helps C++ developers quickly understand and visualize Standard Template Library (STL) containers and algorithms through intelligent hover tooltips.

Perfect for students, competitive programmers, and interview preparation.

🚀 Why STL Lens?

When learning C++, developers often:

• Forget time complexities
• Mix up containers (map vs unordered_map)
• Need quick syntax reminders
• Switch browser tabs repeatedly

STL Lens solves this directly inside VS Code.

Hover. Learn. Continue coding.
