Frequently asked questions
What is the difference between camelCase, snake_case and kebab-case?
camelCase joins words with capital letters (userProfileId) and is standard in JavaScript and Java; snake_case joins with underscores (user_profile_id) and is common in Python and SQL; kebab-case joins with hyphens (user-profile-id) and is used in URLs and CSS class names.
What is the difference between Title Case and Sentence case?
Title Case Capitalises Every Word — used for headings. Sentence case only capitalises the first word of each sentence, like normal prose.
