Snake_case is a naming convention used in programming and data management where words are separated by underscores. This style makes it easier to read and understand variable names, especially when they consist of multiple words. For example, instead of writing "myVariableName," you would write "my_variable_name." This format is commonly used in languages like Python and Ruby. The primary advantage of snake_case is its clarity, as the underscores visually separate the words. This can help prevent confusion and improve code readability, making it easier for developers to collaborate and maintain code. Overall, snake_case is a widely accepted practice in the programming community.
