When coding, text cases become an important factor if you want to maintain your code up to a high standard, following best practices. Different languages follow different naming conventions for variables, constants etc. Here we discuss some of the different types of text casing and their usages in some popular languages.
Camel Case
Spaces are omitted and first letter of each word is capitalized. Looks like a camel with many humps. Other names: Pascal Case, Bumpy Caps, Upper Camel Case.
e.g.: CreateCatDetailsPage, GiveMeAHug, XmlHttpRequest (Note how popular abbreviations are converted.)
C#/VB (VB is case insensitive) method names
Headless Camel Case
Spaces are omitted and first letter of each word except the first word is capitalized. As implied by the name, looks like a camel without its head.
e.g.: getCatDetails, giveMeAHug
Java method and variable names
Snake Case
Looks like snakes, with the words of phrases are separated with undescores (_) rather than spaces.
e.g.: get_snake_details, give_me_a_hug
Python/Ruby function and variable names
Screaming Snake Case
Screaming most of the time means making all the text uppercase. This case is the same as snake case except that all letters are capitalized.
e.g.: SNAKE_SPEED_FACTOR, MAX_SNAKE_AGE
In most programming languages, constants are named using screaming snake case.
Kebab Case / Lisp Case
This one does not have a standard name but called with names like Caterpillar Case, Spine Case, or Hyphenated.
e.g.: max-time-limit, font-family
CSS, Lisp
Train Case
This one is the same as the above, but first letters of all words are capitalized.
e.g.: Train-Case
COBOL Case
Looks more like a screaming Lisp case. Hyphenated words with all caps.
e.g.: MAGIC-NUMBER
COBOL
Studly Caps
Uppercase letters and lowercase letters are mixed. I’m curious whether this is used in any kind of programming.
e.g.: StUdLyCaPs
