Most Common Programming Case Types

camelCase

• camelCase must (1) start with a lowercase letter and (2) the first letter of every new subsequent word has its first letter capitalized and is compounded with the previous word.
• Example: camelCaseVar

snake_case

• snakecase is as simple as replacing all spaces with a "" and lowercasing all the words. It's possible to snake_case and mix camelCase and PascalCase but IMO, but this ultimately defeats the purpose.
• Example: snake_case_var

kebab-case

• kebab-case is as simple as replacing all spaces with a "-" and lowercasing all the words. It's possible to kebab-case and mix camelCase and PascalCase but that ultimately defeats the purpose.
• Example: kebab-case-var

PascalCase

• PascalCase has every word starting with an uppercase letter (unlike camelCase in that the first word starts with a lowercase letter).
• Example: PascalCaseVar
• Note: It's common to see this confused for camel case, but it's a separate case altogether.

UPPER_CASE_SNAKE_CASE

• UPPERCASE_SNAKE_CASE is replacing all the spaces with a "" and converting all the letters to capitals.
• Example: UPPER_CASE_SNAKE_CASE_VAR
