Script Preparation code:

function* backwards(iterable) {
    for (let {
            length
        } = iterable; length--;) yield iterable[length]
}
function reducer(a,b) {
return a+b
}
let string = '1234567890'.repeat(60)

Tests:

backwards reduce
for(let i = 300; i--;)var abc = backwards(string).reduce(reducer)
array.from
for(let i = 300; i--;)var abc = Array.from(string).toReversed().join('')
