# `ItemType` Generic Utility Type

This is to describe the situation where one might want to use the type of an array indirectly.

The ItemType generic is sugar over an existing capability in TypeScript to access the type information of the Array generic
and make accessing that type more legible to the reader. But a few people replied with "huh, I don't think you want to do that",
and to their point, I agree... mostly.

It's almost always better to declare a variable to be of the Array's type directly.

But I'm finding there are situations where I linking a local variable's type to an interfaces's member type to be
more maintainable because it helps the compiler direct me to type errors as I refactor code more effectively.

So here's a concrete use case that is simplified situation where I would use this pattern and I'll explain why afterwards.
