How can you convert a character to its ASCII code in JavaScript? For example, how would you get the code 10 from the newline character "\n" using JavaScript?
Hey! From my experience working with javascript ascii, the easiest way to convert a character to its ASCII code is by using the .charCodeAt() method. For example, if you have the newline character "\n", you can just do "\n".charCodeAt(0), and it’ll return 10. This method returns the Unicode value of the character at the given index, which for basic characters like newline matches the ASCII code perfectly.
Building on that, something I often tell folks diving into javascript ascii is that .charCodeAt() is really flexible, it works on any character in a string by specifying its position. So if you have a string with multiple characters, you can get each one’s ASCII code by changing the index. For your newline "\n", since it’s a single character, "\n".charCodeAt(0) gives you 10, which is the ASCII code for newline. It’s a neat built-in way to handle character-to-code conversions in JavaScript without any extra libraries.
To add a bit more nuance from my experience with javascript ascii, .charCodeAt() doesn’t just return ASCII; it actually returns the UTF-16 code unit, which for ASCII characters (like newline) matches their ASCII code exactly. So, "\n".charCodeAt(0) returning 10 works because newline is in the ASCII range. But if you’re dealing with characters outside the ASCII set, you might want to look into .codePointAt() for full Unicode support. Still, for most ASCII needs in JavaScript, .charCodeAt() is your go-to method - simple, built-in, and efficient.
