Is n divisible by x and y?

A little less parentheses (thanks to de Morgan's law)

Code
Diff
  • const isDivisible = (n,x,y) => !(n%x || n%y)
    • const isDivisible = (n,x,y) => (!(n%x) && !(n%y))
    • const isDivisible = (n,x,y) => !(n%x || n%y)

Power function

Little bit shorter...

Code
Diff
  • const power = (a, b) => a ** b || 1;
    • const power = (a, b) => a === 0 ? 1 : a ** b;
    • const power = (a, b) => a ** b || 1;
