Is if expression or expression statement?

help
1

I have read the documentation:

An expression statement is one that evaluates an expression and ignores its result. As a rule, an expression statement's purpose is to trigger the effects of evaluating its expression.

Is 'if' expression or expression statement?

What is the difference between expressions and expression statements?

the grammar says

ExpressionStatement :
ExpressionWithoutBlock ;
| ExpressionWithBlock ; ?

it just means that you aren't using any value that comes from the expression.

// this is an expression statement
// uncommenting the `let x` part would make `foo.bar()` a non-statement expression
/* let x = */ foo.bar();

I saw examples in the documentation and my assumptions turned out to be correct, but I decided to check

So, it seems like if is an expression than expression statement
