If You Ever Wanted to Know How JavaScript Conditional Operators Executes

A basic conditional operators && OR || execution demo in JavaScript:

1. Using the || operator (OR)
   

   if (confirm('Do you agree, or...') || confirm('...do you wish to revert?')) {
   alert('As you wish...');
   }

   
    
   If you click OK for first confirm() you will not see the second confirm(). When you use the || operator all conditions are checked until one is true.
   
   
   
2. Using the && operator (AND)
   

   if (confirm('Do you agree, and...') && confirm('...do you really confirm to agree?'))  {
   alert('As you wish...');
   }

   
   
   
   
   Even If you click OK for first confirm() you will still see second confirm(). When you use the && operator all conditions are checked and all must be true.
