Type of expressions

[pm771]

If this is another RTFM case, please point me in the right direction.

What is the type of the expression like this: someString == "Yep". Is it Boolean by default?

When we write a cast like Boolean(someString == "Yep"), where are we casting from?

TIA, Eugene

its boolean. Casting using Boolean() in that context is usually just for clarity.
