worstcase-analyzer | vs code extension

Automatically compute and display time and space complexity for JavaScript, TypeScript, JSX, and TSX code as you type in VS Code.

Features

• Automatic Complexity Analysis:
  • Analyzes your JavaScript, TypeScript, JSX, and TSX files for time and space complexity using static analysis.
  • Results are shown as inline decorations at the end of relevant lines (e.g., loops, function calls, conditionals).
• Live Feedback:
  • Complexity is updated automatically as you edit your code.
• Language Support:
  • Only activates for supported language modes: JavaScript, TypeScript, JavaScript React (JSX), and TypeScript React (TSX).

Example

Relevant lines will show decorations like:

for (let i = 0; i < n; i++) { // space: O(1), time: O(n)

Requirements

No special requirements. The extension works out of the box for supported file types.

Extension Settings

This extension does not add any custom settings yet.

Known Issues

• Only works for JavaScript/TypeScript/JSX/TSX files.
• Decorations may not appear for very large files or if VS Code disables them for performance.

Release Notes

0.0.1
