Frequently Asked Questions
What is the difference between camelCase and PascalCase?
camelCase starts with a lowercase letter (myVariable) while PascalCase capitalises the first letter too (MyVariable).
What is kebab-case used for?
kebab-case joins words with hyphens (my-page-title) and is common for URL slugs and CSS class names.
Does converting case change my words?
No. It only changes capitalisation and, for code cases, spacing. The letters and word order stay the same.
Does this tool store my data?
