Introduction

Millions of websites and web applications are built using the JavaScript programming language. In general, JavaScript developers work alongside front-end developers to build the front-end logic to define the behavior of various elements of the visual layout in a web application. 

In addition, JavaScript language is used for connecting with the services running on the backend. The primary responsibilities of a JavaScript developer are to enhance the user experience and the interface by instant response mechanism in the events of user clicks or to fetch data from servers and update the web pages dynamically. 

Typically, these technical professionals are among the most sought-after experts across organizations and industries. A robust JavaScript developer portfolio requires programming skill sets and the knowledge of working on industry-oriented projects. Therefore, it is essential for an individual to deep dive into technical concepts and enhance coding expertise with top online courses.
