Sorting Array Numerical Strings from Highest to Lowest in NodeJS

I'd like to sort an array of Strings which include both Usernames & Points in the same string from Highest to Lowest, without losing the usernames, how do I do this?

I've tried:

arrayName.sort()

However, I have no idea how to make it work with strings! >w<

Here's what I'm working with:

let uwu = [
  "hinata:5000",
  "hiro:3000",
  "karuki:6000",
  "arisu: 4000"
]

Now I'd like to sort it into a new array, from Highest Points to lowest, like below! >w<

Expected Output: 

["karuki:6000", "hinata:5000", "arisu:4000", "hiro:3000"]

Please do help me ! Thank you in advance !

Have a helper function that extracts the digits from the string, then call that function on both elements in the sort callback and return the difference:

const input = [
  "hinata:5000",
  "hiro:3000",
  "karuki:6000",
  "arisu: 4000"
];
const getNums = str => str.match(/\d+/)[0];
input.sort((a, b) => getNums(b) - getNums(a));
console.log(input);
