How to increment letters with JavaScript?
To increment letters with JavaScript, we can use the String.fromCharCode method.
For instance, we write
const c = String.fromCharCode("A".charCodeAt() + 1);
to call String.fromCharCode with "A".charCodeAt() + 1 to return 'B'.
We get the character code of 'A' with charCodeAt.
Then we add 1 to it and use the sum as the argument of fromCharCode to get the letter after 'A'.
Conclusion
To increment letters with JavaScript, we can use the String.fromCharCode method.
