Frequently asked questions
What is camelCase?
camelCase joins words without spaces and capitalises the first letter of each word except the first — for example "myVariableName". It is widely used in JavaScript, Java and Swift.
What is the difference between PascalCase and camelCase?
PascalCase (also called UpperCamelCase) capitalises the first letter of every word, including the first one. It is common for class names and React component names.
When would I use CONSTANT_CASE?
CONSTANT_CASE (all-caps with underscores) is the convention for environment variables and constants in most languages — for example DATABASE_URL or MAX_RETRY_COUNT.
Can I convert multi-line text?
Yes. The conversion applies to the whole block, respecting existing line breaks in the output.
