How to define array type in typescript?

Question

I am using variables of the following type in typescript:

[[string, string], string][]

Is there a way to define this as type so I don't have to repeat this definition everywhere in my code?

Answer 1

You can define a type:

type stringTuple = [[string, string], string][];

And then later use it similar to how you would use a class or interface:

var array: stringTuple;
