The Lazarus IDE gives you error highlighting, code completion, and refactoring tools that rival VS Code. 3. The Debugger is a Time Machine This is the killer feature nobody talks about. When you hit a breakpoint in Lazarus, you can rewind time. You can go backwards up the call stack to see what variable used to be. Try doing that in Python without crying.
