JavaScript JavaScript Loops Working with 'for' Loops Refactor Code with a Loop

The code in script.js logs all even numbers (from 2 to 24) to the JavaScript console. There seems to be a lot of redunda

script.js 
for (let i = 2; i < 24; i = 2) {
console.log(i);
}

Hi Jesus!

This passes:

for (let i = 2; i <= 24; i+=2) {
  console.log(i);
}

Think of the three parts of the for loop as:

1) initialize the loop iterations variable (let i = 2)

2) Keep looping while condition ( i <= 24) (stop after 24, basically)

3) increment the loop iterations variable, in this case by 2 (i += 2) (without incrementing i, the loop will never end)

I hope that helps.

Stay safe and happy coding!
