What is ASCII code used for?

ASCII code converts text characters to numbers (like A=65) so computers process them uniformly, enabling file sharing, networking, and programming basics .

How do I find the ASCII code for a character?

Use JavaScript's charCodeAt() – e.g., 'A'.charCodeAt(0) returns 65. Python? ord('A'). Tables online for quick lookup.

Does ASCII work with non-English characters?

Basic ASCII is English-only (128 chars). Unicode/UTF-8 extends it while keeping ASCII compatible for global text.
