Replace statement by expression

Closes #754

Well, these are actually statements rather than expressions. An expression will always return a value, whereas a statement is just executed code which does not necessarily return anything. In this example for instance, the inline if statement does not return anything, but it still works within v-on.

For some other directives, like v-if, we do require an expression because we use the returned value to check for truthiness.

Does that make sense?

Oh, wow, didn't know that haha

No worries! 🙂 There's so much jargon in computer science and the names are often very poor.

• Declaration
• Statement
• Expression

The meaning of these words is almost identical in human languages, so they seem like very poor choices to describe different things when programming. "Statement" is so general as to be almost useless and "expression" doesn't at all describe what it is. 😂 It should be called a "returnable" or "value producer" or something.

As the songwriter / amateur philosopher Harry Chapin once said:

Sometimes words can serve me well. Sometimes words can go to hell.
