Snake Case is a naming convention used in programming and data management where words are separated by underscores. For example, instead of writing "myVariableName," it would be written as "my_variable_name." This format improves readability, especially in situations where spaces are not allowed, such as in variable names or file names. The use of Snake Case is common in various programming languages, including Python and Ruby. It helps maintain consistency and clarity in code, making it easier for developers to understand and collaborate on projects. Overall, Snake Case is a simple yet effective way to format names in coding.
