You need to install this package
npm i make_leaderboard
You need to import from package
const makeLeaderBoard = require("make_leaderboard")
Now you need to give parameters as a 2d array with name(String) and marks(number) in that package
const LeaderBoard = makeLeaderBoard([["rancho", 45],["chatur", 32],["raju", 30],["farhan", 28],["virus", 32],["joy", 45]])
console.log(LeaderBoard)
Final output will look like
[[ 1, 'joy' ],[ 1, 'rancho' ],[ 3, 'chatur' ],[ 3, 'virus' ],[ 5, 'raju' ],[ 6, 'farhan' ]]
