00:00:01,080 --> 00:00:05,040
Right now, whenever we refresh our application inside the browser, we are getting two warnings.

2
00:00:05,280 --> 00:00:07,080
Let's just take care of those warnings really quickly.

3
00:00:07,420 --> 00:00:11,160
The first one is because we are declaring a piece of state and never actually making use of it.

4
00:00:11,580 --> 00:00:16,800
So at the very top of our app component, I'll find that code set code right there and just delete it.

5
00:00:17,910 --> 00:00:20,010
I'll then go down to our return statement.

6
00:00:22,020 --> 00:00:26,520
Here's our prime element right here where we were previously printing out the bundled code, not doing

7
00:00:26,520 --> 00:00:27,050
that anymore.

8
00:00:27,100 --> 00:00:27,960
I'm going to take that out.

9
00:00:29,820 --> 00:00:34,260
And then finally, the other morning that we have says that we need to make sure that a prime element

10
00:00:34,380 --> 00:00:36,240
has a title property assigned to it.

11
00:00:36,690 --> 00:00:44,610
So I'm just going to put in an iFrame proper of title and just say code review or how about just preview,

12
00:00:44,610 --> 00:00:45,150
for that matter?

13
00:00:46,780 --> 00:00:50,050
Now, if I refresh, but the warnings are gone very good.
