Is {} == true or not in javascript?

Can someone explain why in javascript,

alert({} == true) shows false

if ({}) alert(\'true\') shows true ?

What\’s different in the if condition that changes the result?

I wanted to write some shorthand argument validator obj || (obj = {}); and I was baffled by this discovery.
