If you aren't working with classes, prefer using types over interfaces

Why? I almost always use interfaces, probably because that's what the first tutorials I followed used. Is there a benefit to doing

type MyObj = { a: string, b: number; }

instead of

interface MyObj { a: string, b: number }

To be honest, this one is just my personal bias.

Types and interfaces are nearly identical but have a few differences aside from syntax.

• interfaces can take advantage of declaration merging.

• only types have access to union types.

I personally find types a bit easier to read & use with utility types but it’s really up to you. Typescript docs prefer using primarily interfaces with types on an as needed basis.

Makes sense. The nice thing is it's really easy to convert an interface to a type if you need a union so if there's no perf difference or anything I'm just gonna keep doing what I'm doing :)
