What is the reason behind the occurrence of the CORS Error while utilizing the Place Search feature of the Google Maps API through the `fetch` function?

The CORS error occurs because of the Same-Origin Policy implemented in web browsers, which restricts web pages from making requests to a different domain than the one the page was served from. This is a security measure to prevent malicious websites from accessing sensitive information or performing actions on behalf of the user without their consent. In the case of using the Google Maps API through the fetch function, the request is being made from the client-side JavaScript code in the web page, which is considered a different domain than the Google Maps API server. Therefore, the browser blocks the request and throws the CORS error. To overcome this issue, you need to either use a server-side proxy to make the API request or include the appropriate CORS headers in the response from the server hosting the Google Maps API.
