efficent-Caesar-Cipher

The following questions to CharGPT will introduce more effient way to do Caesar-Cipher.


In JavaScript, is it possible to shift the character code of each character in a string by 1 using regular expression?



OK but it is kind of slow. Executing String.fromCharCode(char.charCodeAt(0) + 1) many times eats a lot of CPU times. Is there any way to make it efficient?


It gives some solutions like:

= Use a Lookup Table (worth to try!)
= Use Typed Arrays for Numeric Operations
= WebAssembly
