The Object.assign() Method in JavaScript - Set default options for functions

The assign() method on the Object constructor in JavaScript is used to merge multiple objects together. You can use it to merge as many objects as you like.
If multiple objects have the same property, the "merged object" will also contain that property but the value of it will come from the last object passed in as an argument. This means it can be used to easily create "default options" within a function.
In this video I take you through examples of how you can use the Object.assign() method and also an example of using it to create default options in a function.
