Code Completion

Code completion is a feature used in live programming that actively reads the user's current code in context to present code suggestions in real-time. The code suggestions may be intended to complete the code for efficiency or improve the code quality.

Code Completion Tools

1. GitHub Co-Pilot: A Code Completion Tool

  • Autocompletion of verbose boilerplate code
    • For example, constructors, getters, setters, and other common code
    • Writing mocks for unit tests
  • Auto-generated code suggestions based on:
    • function names
    • descriptive comments
    • existing code
  • Easy to get started, and works automatically
  • Works with many common languages including Python, JavaScript, TypeScript, Ruby, Go, C#, or C++.
