Deep Dive
Syntax, in the context of programming and markup languages, refers to the set of rules that govern the structure and composition of statements, expressions, and entire code blocks. It defines the correct arrangement of keywords, operators, symbols, and identifiers that are considered grammatically valid within a particular language. Just as human languages have grammar rules to ensure clarity, programming languages rely on strict syntax to allow compilers and interpreters to correctly parse and understand the code, translating it into executable instructions.
