Questions fréquentes

Does Title Case follow style-guide rules?

It capitalizes every word for simplicity. It doesn't downcase short prepositions like 'of' or 'and' - that's a style choice we leave to you.

How is camelCase different from PascalCase?

camelCase leaves the first letter lowercase (myVariable). PascalCase capitalizes it (MyClass). Both are used heavily in JavaScript, Java, and C#.

Does snake_case handle numbers and symbols?

Yes - digits stay in place, and any non-alphanumeric character becomes a single underscore separator.

Is my text sent anywhere?

No. All conversion runs in your browser via native string methods.
