They’re derived from the C syntax, with similar ways of expressing assignments, arithmetic, conditionals, nested expressions, and groups of statements.

(This isn’t strictly true, but non-text languages like Piet and Velato are just obscure for the sake of obscurity.) The UK National Archive recognizes XML and JSON (which is a subset of JavaScript) but doesn’t talk about programming languages as file formats. Exiftool identifies lots of formats but makes no attempt to discern programming languages.
