unicorn/no-magic-array-flat-depth Restriction
What it does
Disallow magic numbers for Array.prototype.flat depth.
Why is this bad?
Magic numbers are hard to understand and maintain. When calling Array.prototype.flat, it is usually called with 1 or infinity. If you are using a different number, it is better to add a comment explaining the depth.
