points.sort(function(a, b){return a - b}); // for ascending
//another way for ascending
points.sort((a,b)=>{
if(a>b){
return 1
}else if(a<b){
return -1
}else{
return 0

const unsorted = ['d', 'd', 'h', 'r', 'v', 'z', 'f', 'c', 'g'];
const sorted = unsorted.sort();

//["c", "d", "d", "f", "g", "h", "r", "v", "z"]
const unsortedNums = [45, 56, 3, 3, 4, 6, 7, 45, 1];
const sortedNums = unsortedNums.sort((a, b) => {
return a - b;
});
