Bug: "Select Catagory" as a input.value causes a waste of a fetch request.

[MohamedBakoush]

For getApis() at app.js the input.value isn't checked to see if a valid category is selected causing the system to waste fetch requests if an invalid category was selected.

Apihouse/app.js

Lines 20 to 26 in 4b3243b

	async function getApis() {
	apiList.innerHTML = "";
	count.textContent = "";
	let category = input.value;
	renderLoader();
	fetch(`https://api.publicapis.org/entries?category=${category}&https=true`)

To Reproduce
Steps to reproduce the behaviour:

1. Selected "Select Catagory" as a Catagory
2. Click "show API's"
3. See "Sorry, Something went wrong !" error

Potential Solution

A simple solution would be to put a validity checker above renderLoader() by exiting getApis() function if a category == "Select Category". As "Select Category" is the only available invalid selectable category from the current option's, making a simple if statement all that's needed to fix this bug.

if (category === "Select Category") return;
