types are so synonymous that there is no reason to use interfaces in TypeScript.

[eyelidlessness]

There are several reasons to use interfaces in TypeScript:

- they perform better at build-time and in editor

- they have more relaxed rules for recursion

- they can help identify complex types and distinguish them from simpler ones

- they’re guaranteed to be usable to enforce class implementations, whereas only simple types can be used

- they’re much easier to read in type errors

> - they have more relaxed rules for recursion Do you have a source for this? I would like to read more.

I would be impressed to see readable, non-trivial TypeScript code that does not use Interface.

Unless you are referring to interface as a concept, and not the keyword in TS.

Can you use the “class MyClass implements MyType” keyword with types?? That might be the only reason if you can’t
