Const primeNumbers = (num) => [...Array(resetNum(num)).keys()]

Question

Const primeNumbers = (num) => [...Array(resetNum(num)).keys()]

.map(x=>x+1)
.filter( x => checker(x) === 2).length;

const checker = (n) => {
let res = 0;
for(let i = 1; i <= n; i++) {
if(n%i === 0) res++;
}
return res;
}

const resetNum = n => n < 0 ? 0 : Math.round(n)
