Title Case capitalizes the first letter of each major word, making it ideal for book titles, blog posts, and formal headings.
What is the difference between camelCase and snake_case?
camelCase joins words with initial capitals (except the first word, e.g. "myVariableName"), whereas snake_case separates words with underscores (e.g. "my_variable_name").
