Atom Token
An atom token is a fundamental, indivisible unit of data or code in programming, often used in lexical analysis and parsing. It represents the smallest meaningful element in a programming language, such as keywords, identifiers, operators, or literals, which are identified by a lexer or tokenizer. This concept is crucial in compiler design and language processing for breaking down source code into manageable components.
Developers should learn about atom tokens when working on compilers, interpreters, or language tools, as they are essential for lexical analysis in parsing source code. It's particularly useful for implementing custom languages, syntax highlighting, or static analysis tools, where understanding tokenization helps in processing and transforming code efficiently.
