camelCase is the standard naming convention in JavaScript, Java, and many other programming languages for variables and function names.
snake_case is common in Python and database column names, where words are separated by underscores.
Title Case capitalizes Every Major Word. Sentence case only capitalizes the first word of the sentence.
