QUESTION

Why can you only use expressions in JSX, not statements?

Asked 2020-Apr-02 at 10:45

Before proceeding, I should mention that yes, I have already read the questions and answers on "Use if statement in React JSX" and its different variants on SO and elsewhere.

However, these posts are more about how to get around without using statements in JSX. I'd like to know why statements aren't allowed in JSX, for which I cannot find any posts on.

Let's start conceptually. What are the definitions of statement vs expression?

A statement does something. An expression evaluates to a value.

JSX is meant to be built up and passed around from one segment of your code to another, eventually ending up as HTML. The name even suggests this "JavaScript to XML" conversion.

The whole point of it is to return a "value" of HTML nodes. JSX kindly allows for expressions, because those help you determine values.

Perhaps it will help to take a closer look at the difference between a ternary expression and an if/else.
