What Is Snake Case?

Snake case, commonly written as snake_case, is a naming convention where words are written in lowercase and separated by underscores.

For example:

Normal text: user account settings
snake_case: user_account_settings

The underscores make individual words easy to identify without using spaces.

 Snake Case vs. Camel Case

Snake case and camel case represent multiple words differently:

snake_case: my_example_text
camelCase: myExampleText

Snake case separates words with underscores, while camelCase removes separators and capitalizes subsequent words.

 Snake Case vs. Pascal Case and Kebab Case

The same text can be represented in several common formats:

snake_case: my_example_text
PascalCase: MyExampleText
kebab-case: my-example-text

Use the format appropriate for the system, code, identifier, or structured text you’re working with.

 Common Uses for Snake Case

Snake case is commonly used for identifiers and structured text in programming, data, configuration, file naming, databases, and other technical contexts.
