Kebab case -- or kebab-case -- is a programming variable naming convention where a developer replaces the spaces between words with a dash.
i.e. new-object or long-function-name.
PascalCase is a naming convention in which the first letter of each word in a compound word is capitalized.
i.e. NewObject or LongFunctionName.
Snake case combines words by replacing each space with an underscore (_) and lowercasing all the words.
i.e. new_object or long_function_name
