diferença entre JS e JSX

JavaScript is just like any normal programming language without any additional library or framework. It can also be referred to as pure/vanilla JavaScript.

On the other hand, JSX is the syntactic sugar in JavaScript, a syntactic sugar is a syntax within a programming language that is designed to make things easier to read or to express. JSX is mostly used in JavaScript along with library/framework support like in ReactJS or ReactNative.
