Pure JavaScript — Building A Real-World Application From Scratch

Modern JavaScript Frameworks like Angular, React and Vue.js makes it very easy to build complex single page web applications. However, using a those frameworks is not mandatory and you can also go with plain and pure JavaScript.

 

Intro

JavaScript is a programming language that browsers can execute, used for defining a page’s behavior, particularly in response to user events. The name is simply a marketing gimmick: It is hardly based on Java at all, but rather on C.

 

Hello world

Because of the wide variety of browsers, working with bare JavaScript is a frustrating chore: The features common to all are rather limited, and even among the common features are frustrating incompatibilities.

While there are many JavaScript frameworks available, we’ll study the most popular among them, called jQuery.
