Using a Template Literal?

Exercise 2 | Step 3

Would there be any reason not to use a template literal for the solution? My solution is only slightly DRYer than Dave's, but I find it easier to read:

for (let i = 0; i < myRandomList.length; i ++) {
  console.log(`Item ${i} in the array is ${myRandomList[i]}`)
}

No reason not to, that's a point of personal preference. In the wild you'll find a lot of times when you can do something multiple ways, especially with Javascript. Usually, try to follow the code guidelines for the project or what fits the situation best.

Thank you. Right, I know you can do something multiple ways. Dave even says that in the video. Just wanted confirmation because it seemed like a more efficient way to use a template literal, but you never know..

Ah okay, sorry I didn't watch the clip, but your way seems completely valid.
