Learn ASCII with Easy Examples in Python and JavaScript

What is ASCII? ASCII (American Standard Code for Information Interchange) is a character encoding system used to represent text in computers using numbers. Each character—such as letters (A–Z, a–z), digits (0–9), and symbols (@, #, etc.)—is assigned a unique numeric value called an ASCII value. Example 'A' → 65 'a' → 97 '1' → 49 '@' → 64 Why ASCII is Important Helps computers store and process text Used in programming and string manipulation Foundation for modern encoding systems like Unicode JavaScript let name = " silambu9391a@gmail.com " ; for ( let i = 0 ; i < name . length ; i ++ ) { console . log ( name [ i ] + " : " + name . charCodeAt ( i )); } How it works name[i] -> gets the character name.charCodeAt(i) -> gets ASCII value of that character Python name = " silambu9391a@gmail.com " for ch in name : print ( ch , " : " , ord ( ch )) How it works for ch in name → loops through each character ord(ch) → gives ASCII value of that character Output
