I often get tripped up learning something new when there are many ways to achieve the same outcome.

You can use object literals to create objects with properties directly. For example:

You can use the Object.create method to create an object that has a specified prototype. For example:

let obj = Object.create(Object.prototype)
obj.name = 'John'
obj.age = 30

You can use class syntax to define a class and then create objects from that class using the new operator. For example:

A good way to learn is to play around in the console or something like RunJS to get a feel for each approach.
