I have only completed the initial phone screen technical interview, so I will update once the full interview process is finished.

Had about a one-hour technical interview that discussed my personal experience with a particular front-end JavaScript framework.

I believe the next step would be in-person interviews at their headquarters.

The coding exercise consisted of creating a JavaScript class called Model that would expose the following methods:

• get
• set
• has
• on
• trigger

The class signature would be something like the following:

javascript const Woof = new Model({id:133, type: 'dog', name:'Spot' });

The has method would take a property name and check if the model has that particular property, returning true or false.

The get method would take a property name and return its value if it exists. It should return null if not.

The set method would take a property name and a value, and set that property's value if the property exists.

The on method would allow for the addition of an event to the class and a callback function.

The trigger method would allow the "triggering" of a particular event and pass any number of parameters to the callback function.

You can use ES5 or ES6 syntax.
