Frequently asked questions
How does the converter split words?
It splits on spaces, hyphens, underscores, and the boundary between a lowercase letter and an uppercase letter (so 'myVariableName' is recognized as three words), then rebuilds each casing style from those words.
When would I use snake_case vs kebab-case?
snake_case is common for variable and file names in Python, Ruby, and databases. kebab-case is common in URLs, CSS class names, and command-line flags.
