Frequently asked questions
- What's the difference between Title Case and sentence case?
- Title Case capitalises the first letter of every word ("The Black Dog"). Sentence case only capitalises the first letter of the first word ("The black dog"). Title Case is typical for titles and headings, sentence case is normal writing.
- What are camelCase, snake_case, and kebab-case?
- Naming conventions used in programming. camelCase joins words without spaces and capitalises the following ones ("myVariable"). snake_case uses underscores between lowercase words ("my_variable"). kebab-case uses hyphens ("my-variable"). Each language or system tends to prefer one convention.
- How are accents handled?
- Preserved. Uppercase accented letters (Á, É, Ç) and lowercase (á, é, ç) are converted correctly. To strip accents completely, use the accent remover tool.
