Syntax {Parser}

A syntax parser, often referred to simply as a parser, is a crucial component of a programming language compiler or interpreter. Its main function is to analyze the structure of source code written in a programming language and transform it into a format that the computer can understand and execute. In other words, a syntax parser ensures that the code is grammatically correct and adheres to the rules of the programming language

Syntax {Validation}

The parser checks the code for correct syntax and enforces the rules of the programming language. It ensures that the code is written in a way that the language's compiler or interpreter can understand.

Structure {Analysis}

The parser determines the hierarchical structure of the code, identifying elements like functions, loops, conditionals, variables, and more. This structure is crucial for later stages of compilation or interpretation.


Syntax tree produced by parser component is typically used as an intermediate step during a source code translation/compilation. Generally, a syntax tree is not intended to be read by software engineer.
