What is the difference between this two type definitions?

type objectArray = [object]

type objectArray = object[]

CodePudding user response：

[object] is a tuple. It's the type of an array with a single value in it, and the value must be an object.

object[] is the same as Array<object>. It's the type of an array with any number of values, where any such values must be object.

All tuples are arrays, but a tuple is a more restrictive type of array, with a specified number of elements.
