Pythagorean Triples

var a = 1;
var b = 1;
var c = 1;
var range = 20;

console.log("Here are some Pythagorean Triples:")

for(let i = 0; i < range; i++) {
    for(let i = a; i < 500; i++) {
        b = i;
        c = Math.sqrt(Math.pow(a,2) + Math.pow(b,2));
        if (Math.floor(c)==c){
            console.log(a,b,c);
        }
    }
    a++;
}
