Undefined or not initialized variables with strange behavior

[EduFrazao]

Hi. Undefined or not initialized variables presents a strange behavior in version 1.7.14

Like this code:

var x = undefined;

if (!x) {
    // Never enters here
}

Not initialized variables also reports its types as strings

var x;
print(typeof x)

This codes prints: "string"

Is this somehow expected?

Edit note:
With 1.7.13 works fine.

I tested in the current 1.7.15 snapshot, indeed:

var x = undefined;
if(x) print(x)  //yields nothing
if(!x) print(x) //prints "undefined"

I also checked Boolean(undefined). This evaluates to false as it should, so maybe there's something wrong with the if logic.
For the second issue, mine printed undefined so this was probably fixed.

I'll add these as test cases when I familiarize myself more with the repo.

Hi. Thanks for testing.
Did you test the output of "typeof x" after set it as undefined?
