SnakeCase is a way of writing words where each word is joined together with an underscore (_) instead of spaces. For example, the phrase "hello world" would be written as "hello_world". This style is often used in programming and computer science to make variable names easier to read, especially when they contain multiple words. Using SnakeCase helps avoid confusion that can arise from spaces or special characters in names. It is particularly popular in languages like Python and Ruby, where clear naming conventions are important for writing clean and understandable code. Overall, SnakeCase is a simple yet effective way to format text in a readable manner.
