Problem
We are required to write a JavaScript function that takes in a lowercase alphabet string. The index of ‘a’ in alphabets is 1, of ‘b’ is 2 ‘c’ is 3 … of ‘z’ is 26.
Our function should sum all the index of the string characters and return the result.
Example
Following is the code −
const str = 'lowercasestring'; const findScore = (str = '') => { const alpha = 'abcdefghijklmnopqrstuvwxyz'; let score = 0; for(let i = 0; i < str.length; i++){ const el = str[i]; const index = alpha.indexOf(el); score += (index + 1); }; return score; }; console.log(findScore(str));
Output
Following is the console output −
188
