snake_case replaces spaces with underscores and lowercases everything. Example: 'Hello World' → 'hello_world'. Common in Python and database column names.
What is kebab-case?
kebab-case replaces spaces with hyphens and lowercases everything. Example: 'Hello World' → 'hello-world'. Standard for CSS class names and URL slugs.
