Tips and common questions
What is the difference between Title Case and Sentence case?
Title Case Capitalises The Main Words, like a book title. Sentence case only capitalises the first word, like a normal sentence.
What are camelCase, snake_case and kebab-case?
They are ways of joining words without spaces, used in programming and web addresses. camelCase looks like myFileName, snake_case like my_file_name, and kebab-case like my-file-name.
What does Detect Case do?
It looks at your text and tells you which style it is already in, which helps when you are cleaning up code or data.
What does slugify do?
It makes text safe for a web address: lowercase, no special characters, and hyphens instead of spaces. For example, "My Best Post!" becomes my-best-post.
