return true/false inside function doesn't show up in output

I run the following
`function returntrue(buol){`
` if (buol === true){`
` return true;`
` }`
` return false;`
`}`
`returntrue(false);`

And the output I get is
`[Done] exited with code=0 in 0.356 seconds`
Shouldn't I get **false**? I am confused.
What am I doing wrong?
