JavaScript false/null var inside if clause

Question

What kind of variables will NOT pass through this:

if(myVar){//code}

Boolean false? NULL? Boolean false and NULL? Anything else?

Thank you.

Answer 1

All the following falsy values as:

• null
• undefined
• NaN
• 0
• "" _{(an empty string)}
• false

Anything else converted to Boolean will yield true.
