Answer 2

An event driven program in JavaScript to display even numbers from 1 to 50 is the following:

function printEven(50) {

 for (let i=1; i<=50; i++) {

   if(i % 2 === 0) {

     console.log(i);

   }

 }

}

The output of the above written program will be something of this manner

2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32 34 36 38 40 42 44 46 48 50
