Different programming languages and communities have their own conventions and naming cases for variables, functions, and other elements. Here are some commonly used naming cases in programming:

Camel Case

In camel case, each word is capitalized except for the first word. The first letter of the first word is lowercase, while the first letter of each subsequent concatenated word is capitalized. Example: myVariableName.

Pascal Case

Similar to camel case, but the first letter of each word is capitalized. Pascal case is often used for naming classes and types. Example: MyClassName.

Snake Case

In snake case, words are separated by underscores, and all letters are lowercase. It is commonly used in languages like Python for variable and function names. Example: my_variable_name.

Kebab Case

Words are separated by hyphens, and all letters are lowercase. It is frequently used in URLs or file names. Example: my-variable-name.

Upper Case

All letters are capitalized, and words may be separated by underscores or other separators. It is often used for constants or predefined values. Example: MY_CONSTANT_VALUE.

Hungarian Notation

Hungarian notation involves prefixing variable names with characters indicating their data types or meanings. This convention is less common nowadays but was popular in older programming styles. Example: strName for a string variable.

It’s important to note that different programming languages and communities may have specific naming conventions and cases that they prefer. It’s always a good practice to follow the established conventions within the language or community you are working in to maintain consistency and readability in your code.
