Uses deprecated APIs
"Uses deprecated APIs" essentially, means that your webpage is using APIs that are deprecated, which can lead to compatibility issues and negatively impact the user experience.
How to fix it
The solution is to remove or replace the deprecated APIs. Here's how:
Step 1: Identify Deprecated APIs
First, you need to identify the deprecated APIs that your webpage is using. You can use Chrome DevTools for this. Open DevTools, go to the 'Console' tab, and look for warnings about deprecated APIs.
Step 2: Remove or Replace Deprecated APIs
Once you've identified the deprecated APIs, you need to remove or replace them. This might involve updating your code to use newer APIs, or removing features that rely on deprecated APIs.
// Before
var xhr = new XMLHttpRequest();
xhr.open('GET', 'https://example.com', true);
xhr.send();
// After
fetch('https://example.com');
In this example, we've replaced the deprecated XMLHttpRequest API with the newer fetch API.
Step 3: Test Your Changes
For an even better solution, consider testing your changes to make sure they don't break any functionality. This can help ensure that your site still works as expected without the deprecated APIs.
