The whole process of content rendering from frontend content to JavaScript or other programming languages that are relatable to frontend is provided by the WordPress REST API, which provides us with the ability to transfer the said process of frontend. JavaScript will then provide us with the opportunity to increase the interactivity and its performance, thus the arisen necessity of making use of it.
This chapter will mainly focus on the process of creating the front-end system for an application or website, all this without disrupting the use of WordPress for managing the content, accomplished by making use of the WordPress REST API. The following chapters will then cover the creation of single page websites, which are powered by the very same WordPress REST API architecture in such a way that its entire frontend capabilities are divided from WordPress.
