 You must write all of the code from scratch. You are not allowed to rely on any frameworks or libraries like React, Vue, Svelte etc.
 
 #### Fetching the data

 In order to get the information, you should use `fetch`.
 When you use `fetch` in JS, it always returns a `Promise`. We will look more deeply into that later on. For now, take a look at this:
 
 ```js
 // This function is called only after the data has been fetched, and parsed.
-const loadData = heroes => {
-  console.log(heroes)
-}
+const loadData = (heroes) => {
+  console.log(heroes);
+};
 
 // Request the file with fetch, and the data will be downloaded to your browser cache.
-fetch('https://rawcdn.githack.com/akabab/superhero-api/0.2.0/api/all.json')
+fetch("https://rawcdn.githack.com/akabab/superhero-api/0.2.0/api/all.json")
   .then((response) => response.json()) // parse the response from JSON
-  .then(loadData) // .then will call the `loadData` function with the JSON value.
+  .then(loadData); // .then will call the `loadData` function with the JSON value.

 - A slick design. Spend some time improving the look and feel by playing around with CSS. Have fun with it.
 - Modify the URL with the search term, so that if you copy and paste the URL in a different tab, it will display the same column filters. If you have implemented detail view, the state of which hero is displayed should also form part of the URL.
