Short circuit means that the expr part above is not evaluated, hence any side effects of doing so do not take effect (e.g., if expr is a function call, the calling never takes place). This happens because the value of the operator is already determined after the evaluation of the first operand. See example:

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

The following expressions might seem equivalent, but they are not, because the && operator is executed before the || operator (see operator precedence).

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