Backus-Naur Form

Backus-Naur Form (BNF) is a formal way to describe the rules of a language, particularly programming languages or data formats. It uses symbols to define how strings of text are constructed. For example, it specifies how sentences can be formed using different words and structures. BNF is useful for creating compilers and interpreters, helping computers understand the syntax of programming languages. By providing clear grammar rules, it enables programmers to write code that the computer can interpret correctly, ensuring consistent communication between humans and machines.
