Use a for-loop to loop through the given string to get ASCII code, and use charCodeAt() method. A charCodeAt() method retrieves a Unicode value (or ASCII code) for a character at a specific position in a string.
Assign that Unicode value to a variable and add that value into the array.
for(let i = 0; i < s.length; i++){
let code = s.charCodeAt(i);
charCodeArr.push(code);

let code = s.charCodeAt(i);
charCodeArr.push(code);
}
return charCodeArr;
}
