Following the rules, stackexchange/SoftwareEngineering is about this topics:
If you have a question about...
- Software development methods and practices
- Requirements, architecture, and design
- Quality assurance and testing
- Configuration management, build, release, and deployment
...then you're probably in the right place to ask your question.
So, asking a question about differences of code checks in Typescript vs checks in the Js JIT-Compiler are not appropriate in this forum? Why?
