The String normalize() method

New Course Coming Soon:

Get Really Good at Git

Find out all about the JavaScript normalize() method of a string

Unicode has four main normalization forms. Their codes are NFC, NFD, NFKC, NFKD. Wikipedia has a good explanation of the topic.

The normalize() method returns the string normalized according to the form you specify, which you pass as parameter (NFC being the default if the parameter is not set).

I will reuse the MDN example because I’m sure there is a valid usage but I can’t find another example:

'\u1E9B\u0323'.normalize() //ẛ̣
'\u1E9B\u0323'.normalize('NFD') //ẛ̣
'\u1E9B\u0323'.normalize('NFKD') //ṩ
'\u1E9B\u0323'.normalize('NFKC') //ṩ
Are you intimidated by Git? Can’t figure out merge vs rebase? Are you afraid of screwing up something any time you have to do something in Git? Do you rely on ChatGPT or random people’s answer on StackOverflow to fix your problems? Your coworkers are tired of explaining Git to you all the time? Git is something we all need to use, but few of us really master it. I created this course to improve your Git (and GitHub) knowledge at a radical level. A course that helps you feel less frustrated with Git. Launching Summer 2024. Join the waiting list!
