JavaScript JavaScript Loops, Arrays and Objects Simplify Repetitive Tasks with Loops Refactor Using a Loop

simply repetitive tasks with loops

The code below logs all of the even numbers from 2 to 24 to the JavaScript console. However, there's a lot of redundant code here. Re-write this using a loop.

script.js 
console.log(2);
console.log(4);
console.log(6);
console.log(8);
console.log(10);
console.log(12);
console.log(14);
console.log(16);
console.log(18);
console.log(20);
console.log(22);
console.log(24);
for ( i=2 ; i<24 ; i+=2 ) {
  console.log(i); 
}

for (var i = 2; i < 26; i += 2) { console.log( i ); }

Hi there,

You are supposed to delete all the previous code and you have to take into account that the number 24 also needs to be displayed.
