Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

JetBrains IntelliJ IDEA

  • High memory consumption and slower startup time compared to lightweight editors like Visual Studio Code
  • Refactoring can sometimes increase code line count and doesn't effectively support all modern programming languages
  • Occasionally misses dependencies between files requiring full rebuilds for consistency
  • Expensive subscription costs for Ultimate edition compared to open-source alternatives like Eclipse
  • Not all class name references are updated reliably when using search and replace functionality

TypeScript

  • Requires build/compilation step; adds complexity to development workflow
  • Performance slower than compiled languages like Rust or Go when running on same hardware
  • Type safety only at compile-time; runtime errors still possible if types are misused
  • JavaScript ecosystem requires understanding both TypeScript and JavaScript
