Introduction

In Vue.js development, a client’s web browser reads HTML and JavaScript and renders web pages based off of the instructions that the developer writes for it. But the web page or application not only needs to process data; it also needs to process user interactions. To do this, developers use events in JavaScript that execute code when the user interacts with HTML elements.

An event can capture any user interaction with a user interface button or a physical keyboard or mouse. In JavaScript, you would create event listeners that wait for that event to occur and then execute a block of code. In Vue.js, you are not required to listen for an event; that is done automatically with the v-on: directive.

In this tutorial, you will use events in Vue to create an application of airport codes. When the user selects an airport code, the app will add that airport to a “favorites” collection. By following along with this project, you will learn what events are, how to use Vue’s built-in events, and how to create your own custom events.
