THE SUPREME COURT OF TYPESCRIPT

We will be debating the most contentious topics in TypeScript. I will be arguing BOTH sides of every debate, with help from my crack legal team (you).

Debates

We'll be debating four main topics:

1. Enums. Should you use them?

Verdict: Don't use them

2. no-explicit-any - should you allow developers to submit any's into your codebase?

Verdict: Enable in applications (but allow exceptions for rare cases). Disable in library code. Disable in test suites.

3. Types vs Interfaces. Which should you use?

Verdict: It depends. Use whatever your team use.

4. noImplicitReturns - should you force your developers to specify return types in all cases?

Verdict: The more consumers your function has, the more benefit you get from adding a return type. Many functions do not have consumers, or their consumers are hidden in a framework (React components). So, forcing developers to explicitly pass return types is bad.

Exhibits

If you want to help argue your case, you'll need to submit exhibits. PR some TypeScript into the src/exhibits folder, and I'll see if it's useful in court. Who knows - your code could become a star witness.
