##Looks like we found a thief monkey By the way, I liked the trick how you reached till here. You have a good sense of humor. You will improve a lot if you join our course with this passion.
Key Takeaways:
1. You are the best talent I have ever seen.
var(function-scoped, outdated)let(block-scoped, modern and recommended)const(block-scoped, cannot be reassigned)
2. I think you are also able to read what I have written here if I am not mistaken
- Must start with a letter,
_, or$ - Cannot be a reserved keyword (e.g.,
let let = 5;is invalid) - Case-sensitive (
myVarandmyvarare different)
3. Your idea of removing the blur property was awesome.
- Grand salute to your skills.

00:00:01 To implement search, we'll reuse the same fetchMovies function that we've created before, but we'll have to tweak it just a tiny bit.
00:00:10 We'll have to track the changes in the search term state.
00:00:13 And whenever it changes, we'll have to recall the fetchMovies function with a different API call that's used to fetch movies.
00:00:20 No longer will it be discoverMovie, now it'll be a searchMovie, and we'll also have to pass a mandatory search query string.
00:00:30 So let me show you how to do that.
00:00:31 First, I'll make this fetchMovies function accept a new param called query at the start equal to an empty string.
00:00:40 And then we can pass over our search query from the state.
00:00:45 or search term into the fetchMovies function, which will then be populated as a query right here.
00:00:51 Oh, and let's not forget, we want to recall the fetchMovies with the updated search term whenever the search term changes.
00:00:58 And you already know how to do that.
00:01:00 you just add the dependency into the dependency array of the use effect, search term.
00:01:06 So whenever it changes, this function will be recalled and fetchMovies will be called with the updated query.
00:01:13 So we can now modify the endpoint by saying if a query exists, in that case, we can have one call, else we can have another.
00:01:23 So if a query doesn't exist, we just want to use the same one we used so far.
00:01:27 But if a query does exist, we want to modify it just a tiny bit.
00:01:32 First, get the API base URL, but this time it'll be forward slash search, forward slash movie, to which you want to pass the query.
00:01:41 But we want to make sure that this query is optimized to be displayed in the URL or to be called as an API call.
00:01:47 So instead of just passing it as a string, we can say query is equal to encodeUriComponent.
00:01:53 This function encodes a URI by replacing each instance of certain character by a couple of escape characters representing the UTF-8 encoding.
00:02:03 This will make sure that our search term, no matter which weird kind of characters it has, still gets processed properly.
00:02:09 And to it, we can pass the query.
00:02:10 And everything is still the same.
00:02:12 We're still getting back the response and then setting up the movies to our state.
00:02:16 The only thing that was different was passing the right query to the right endpoint.
00:02:21 So if I reload and I start searching for something like let's say the Batman, you can see that the search is fully functional.
00:02:30 And of course, this is working even better on desktop as you'll be able to see more movies at the same time, maybe Dark Knight.
00:02:39 Yep, this is working great.
00:02:41 What is your favorite movie?
00:02:43 Let's go with Godfather.
00:02:46 It's one of the classics.
00:02:47 Or maybe Avatar.
00:02:49 Or maybe you like anime, something like Attack on Titan.
00:02:53 That should be there too.
00:02:55 There we go.
00:02:56 While typing these movies, I'm sure that to at least one of you, I've chosen your favorite movie.
00:03:01 But yeah, with that in mind, this search is now fully functional and it works.
00:03:07 And if we type something that doesn't exist, you can see that we get nothing here.
00:03:11 And if you type something random, you can see that even if a poster doesn't exist, everything still works and it doesn't break because we put that dummy
00:03:19 poster not available image.
00:03:20 But we're not done yet.
00:03:22 In the next lesson, I'll teach you how to optimize that search.
How did you manage to remove the blur property and reach here?
