Question

Write a event driven program in JavaScript to display even numbers from 2 to 50

Answer 1

Answer:

function* range(begin, end, filter, ite = 1) {

      for (var x = begin; x != end; x += ite) {

              if (filter(x)) {

                      yield x;

              }

      }

}

 

function is_even(i) {  return i % 2 == 0;  }

 

window.onload = function() {

 for (var i of range(1,50,(i) => is_even(i))) {

      console.log(x);

}

}

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
