1) Knowledge of HTML and CSS

We all are aware that JavaScript at its core is a robust front-end development technology. JavaScript essentially provides responsiveness for the web page. A web page is never considered as responsive until there is a flow of data from both the sides, i.e. from server to browser and vice-versa. Hence, it becomes important for a JavaScript developer to possess an extensive knowledge of HTML and CSS.

2) Proficiency in a Server-Side Scripting Language

As mentioned in the previous point, JavaScript is a useful client-side technology. Though, it has found implementation on the server-side because of Node.js, yet it is not the easiest option to apply certain modern or complex functionality, which a server-side language like PHP can handle efficiently. Hence, it is advisable for a JavaScript developer to possess a strong knowledge of at least one server-side scripting language which will broaden his scope not only as a developer but also as a job seeker.

3) Knowledge of Design Principles

Today, static websites stand no chance against dynamic ones. Often, JavaScript developers focus more on the functionality of a website or web application but do not take in to consideration the design of a website. A website provides a good user experience only when a user-friendly functionality is complemented with an intuitive web design. These two aspects of web development go hand in hand. Hence, it is important for a JavaScript developer to apply modern design principles and prudently use the various UI elements in his web development projects.

4) Contributing to Open-Source Projects

This point is especially meant for freelance JavaScript developers but is also very important for other JavaScript developers in general. Today, most of the large-scale companies pay attention to this aspect while hiring a JavaScript developer. Being an active member in the open-source community of JavaScript developers is considered as a positive trait by employers. It is bound to be so since it shows that as a developer, one is committed as well as efficient in his job. So, as a JavaScript developer one must strive to contribute to the open-source projects by pulling projects from popular GIT repositories like GitHub. As we all are aware, some of these projects have grown to become one of the most trending, open-source libraries and frameworks, like jQuery and Twitter Bootstrap.

5) Knowledge of Plugin Integration

The importance of plugins in the development of open-source technology projects is prominent. A plugin is essentially a piece of JavaScript code which can be integrated in to a web development project. Moreover, packaging a common function within a JS plugin makes it more portable allowing users to easily integrate a plugin in to any number of projects within a short period of time. Plugins help extend the features of a JavaScript application. A JavaScript developer should possess strong knowledge about plugin usage and integration which can allow him to introduce newer features and better functionalities in to his web development projects.

One such website is StackOverFlow, which is a popular Q&A (question and answer) website for developers. As a JavaScript developer, one can post answers to various questions posted on this website. Such platforms are ideal for demonstrating one’s knowledge and skills.

Modern browsers come equipped with strong DevTools. Apart from helping a JavaScript developer to debug his code, these tools provide additional functionalities like checking web performance for his page and providing local storage options. There are several work flow and scaffolding tools which assist JavaScript developers in their projects and helps automates much of their work. It is beneficial to use these automation tools but as a JavaScript developer, one should not let these tools to ruin your expertise in programming.

It is never only coding that a JavaScript developer needs to do while working on a project. Another important job of a JavaScript developer is testing his software application.

It also helps in saving time which can allow developers to look in to other important tasks.
