is-alphabetical is a small ESM JavaScript/TypeScript function that checks whether a given character is an ASCII alphabetical character (matching [a-z], case insensitive). It returns true for letters like “a” and “B”, and false for non-letters, and is useful when you need this check as a shared helper across multiple packages.
