Mapping string to Numerals in JavaScript
We are required to write a JavaScript function that takes in a string. It should print out each number for every corresponding letter in the string.
For example:
a = 1 b = 2 c = 3 d = 4 e =5 . . . y = 25 z = 25
Note: Remove any special characters and spaces.
So, if the input is −
"hello man"
Then the output should be −
"8,5,12,12,15,13,1,14"
Example
The code for this will be −
const str = 'hello man'; const charPosition = str => { str = str.split(''); const arr = []; const alpha = /^[A-Za-z]+$/; for(i=0; i < str.length; i++){ if(str[i].match(alpha)){ const num = str[i].charCodeAt(0) - 96; arr.push(num); }else{ continue; }; }; return arr.toString(); } console.log(charPosition(str));
Output
The output in the console will be −
"8,5,12,12,15,13,1,14"
