Shortest code to reverse array

I need to find the shortest code for reversing an array and at the moment I have this:

weirdReverse=a=>a.sort(()=>1)

This is a codewars challenge and the length of this is 29 bytes. I need to have a length <=28 so I need to remove 1 byte and I can't change this part:

weirdReverse=a=>a

And I can't use reverse().

You can use a named parameter instead of braces, like so:

weirdReverse=a=>a.sort(b=>1)

You can golf one byte off your anonymous arrow function by specifying an unused parameter instead of () to indicate no named parameters, bringing the total down to 28 bytes:

weirdReverse=a=>a.sort(_=>1)
