# JavaScript Google Maps Distance Matrix API Example to Find Distance & Time Between Two Addresses

In this tutorial, I will give you the complete JavaScript source code of the Google Maps Distance Matrix API example. You will learn how Google Maps Distance Matrix API measures the distance and calculates the journey duration between multiple locations (origins and destinations).

First of all, create a new HTML5 file on your computer and copy/paste the below source code into it.
