Solution to Total amount of points Question:

The simple solution to the ‘Total amount of points’ question is to first loop through the strings given in the games array, if the 0th index of games[i] > 2nd index of games[i] we have to add 3 to the score, else if they are equal we need to add 1 to the score. Finally, return the score value.

function points(games) {
  let sum=0;
  for (let i=0; i<games.length; ++i)
    if (games[i][0]>games[i][2])
    if (games[i][0]==games[i][2])
  return sum;
//solution style 1 - easy to read and understand

function points(games) {
  let result = [];
  let score = 0;
  games.forEach(x => {
    result = x.split(":");
      score += 3;
    else if(result[0]==result[1])
      score += 1;
      score += 0;
  return score;
//solution style 2 - single line

const points=games=>games.reduce((output,current)=>{
return output += current[0]>current[2] ? 3 : current[0] === current[2] ? 1 : 0;  },0)
