Place Autocomplete Element

Page Summary

This code implements an autocomplete widget that allows users to search for places.
Upon place selection, it displays details like name, address, and location.
The sample is provided in both TypeScript and JavaScript, with the JavaScript compiled from the TypeScript version.
Users can interact with a live demo through JSFiddle or Google Cloud Shell and clone the sample code for local execution.
Developers are encouraged to explore the Place Overview component for displaying comprehensive place information using a pre-built UI.

This example adds an Autocomplete widget to a web page, and displays the results for each selected place.
