Backus-Naur Form (BNF)

Backus-Naur Form (BNF) is a formal notation used to define the syntax of programming languages and data formats. It uses a set of rules to describe how symbols (like words or characters) combine to form valid structures. Think of it as a precise recipe or blueprint that specifies the correct order and arrangement of elements, much like grammar rules in a language. BNF helps computers and developers understand and verify that code or data follow the correct format, ensuring consistent interpretation and processing.
