syntax vs. semantics

Syntax refers to the arrangement and rules for how words or symbols are structured in a language or code, similar to grammar rules in a sentence. Semantics relates to the meaning or interpretation of those words or symbols, determining what the sentence or code communicates. In programming, syntax ensures the code is written correctly, while semantics ensures the code does what it's supposed to do. Think of syntax as the "grammar" of a language and semantics as its "meaning." Proper syntax guarantees the code runs, but correct semantics guarantees it performs the correct task.
