This is the solution for the Codewars *Total amount of points* question in Javascript with a simple & easy to understand code and explanation.

### Task:

Our football team finished the championship. The result of each match looks like “x:y”. Results of all matches are recorded in the collection.

For example: `["3:1", "2:2", "0:1", ...]`

Write a function that takes such collection and counts the points of our team in the championship. Rules for counting points for each match:

- if x>y – 3 points
- if x<y – 0 point
- if x=y – 1 point

## 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])
sum+=3;
if (games[i][0]==games[i][2])
sum+=1;
}
return sum;
}**

```
//solution style 1 - easy to read and understand
```**function points(games) {
let result = [];
let score = 0;
games.forEach(x => {
result = x.split(":");
if(parseInt(result[0])>parseInt(result[1]))
score += 3;
else if(result[0]==result[1])
score += 1;
else
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)**
