Day 7 is counting the sum of vowels and consonant in a single string. A vowel will value of 1 and consonant will give value of 2.

For example, `abcde`

will give value of 8.

`a=1, b=2, c=2, d=2, e=1`

so `1+2+2+2+1`

is 8.

This is the JavaScript solution

```
function countVowelConsonant(str) {
let strArray = str.split('');
let vowels = ['a','i','u','e','o'];
let result = strArray.reduce((total, letter) => {
return vowels.includes(letter) ? total + 1 : total + 2;
}, 0);
return result;
}
```
