Typescript difference between using type check and generic

Question

I'm in the middle of a typescript course. We're learning generics and the following example is shown

const hobbies: Array<string> = ['coding', 'eating']

Now before I learned to check an array of type using the following syntax

const hobbies: string[] = ['coding', 'eating']

Can anyone explain me what the difference is?

Those two mean the same thing. So i can see that as a useful example for introducing the concept of generics, since it takes a concept you're already familiar with (arrays) and shows another way it can be done. But generics can also be used in a broader range of contexts than just arrays.

What's the preferred method you think? – Miguel Stevens Jan 20 '19 at 03:34
The way I handle it: simple types with `string[]`, more complicated types (e.g. union types, in-line object types) w/ `Array` since it’s more readable in my opinion. – inyono Jan 20 '19 at 03:50
