Questions
What is camelCase?
A naming style where words are joined without spaces and every word after the first starts with a capital: firstName, userEmailAddress. It is the convention for variables in JavaScript and Java.
What input does the converter understand?
Spaces, hyphens, underscores, and existing case boundaries all count as word breaks — "user_name", "user name", and "UserName" all become "userName". Each line converts separately.
