Frequently asked questions

What is the difference between Title Case and Sentence case?

Title Case capitalises the first letter of every word; Sentence case only capitalises the first letter of each sentence.

What are camelCase and snake_case for?

They are naming styles used in code - camelCase for variables in many languages, snake_case in Python and databases, kebab-case for CSS classes and URL slugs.

Is my text uploaded?
