Pattern: Length-based array indexing

Issue: -

Description

Using negative indices provides a more concise and readable way to access elements from the end of an array, compared to using length-based calculations like array.length - n.

Examples

Example of incorrect code:

foo.slice(foo.length - 2, foo.length - 1);
foo.at(foo.length - 1);

Example of correct code:

foo.slice(-2, -1);
foo.at(-1);
