Description
The at() method returns an indexed element from an array.
The at() method returns the same as [].
The at() method is supported in all modern browsers since March 2022:
Note
Many languages allows negative bracket indexing like [-1] to access elements from the end of an
object / array / string.
This is not possible in JavaScript, because [] is used for accessing both arrays and objects. obj[-1] refers to the value of key -1, not to the last property of the object.
The at() method was introduced in ES2022 to solve this problem.
Syntax
array.at(index)
