camelCase joins words together with no spaces, capitalizing the first letter of each word except the first. Example: "hello world" becomes "helloWorld". It is widely used in JavaScript and Java variable names.

snake_case joins words with underscores and uses all lowercase. Example: "hello world" becomes "hello_world". It is common in Python and database column names.

kebab-case joins words with hyphens and uses all lowercase. Example: "hello world" becomes "hello-world". It is used in CSS class names and URL slugs.

What does "alternating case" do?

Alternating case toggles between lowercase and uppercase on every character: "hello" becomes "hElLo". It is often used for humorous or emphasis purposes.

Does it handle special characters?

Yes. camelCase, snake_case, and kebab-case strip non-alphanumeric characters when joining words. Other formats preserve punctuation and symbols.
