camelCase is commonly used in programming for variable names and function names. The first word is lowercase, and subsequent words have their first letter capitalized with no spaces (e.g., ‘myVariableName’).
What is snake_case used for?
snake_case is another programming convention where words are separated by underscores and all letters are lowercase (e.g., ‘my_variable_name’). It’s commonly used in Python, Ruby, and database naming.
