“||” Ответ

true || false && false      // returns true, because && is executed first
(true || false) && false    // returns false, because operator precedence cannot apply

function A(){ console.log('called A'); return false; }
function B(){ console.log('called B'); return true; }

console.log( B() || A() );
// logs "called B" due to the function call,
// then logs true (which is the resulting value of the operator)
