The explanation is in the method valueOf() . When a is called returns valueOf taht is this.num += 1; a == 1 //first a.num increases in 1 then check a == 1 and return true //now a.num has 1 a == 2 //a.num increase in 1 one more time, a.num has 2, and return true Please read https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/valueOf

It's return true because a is a not null object so if you try a==0 you will see false ...
