Qualifications for a Senior JavaScript Developer

The first step to securing your dream job as a qualified Senior JavaScript Developer is to equip yourself with the necessary skills and abilities. In order to successfully fulfill the role of a Senior JavaScript Developer, it is important to possess the following abilities:

  1. JavaScript Fundamentals

    JavaScript is an integral component of the language as it is supported by both client-side and server-side environments. It provides developers with components, libraries and other features that enable them to build applications quickly and efficiently. It is composed of two distinct components: client-side JavaScript (CSJS) and server-side JavaScript (SSJS). The CSJS contains fundamental elements which are beneficial to developers. Meanwhile, the SSJS works for both parties and provides a robust environment for the development process.
  2. Redux

    Redux is a free and open-source JavaScript library that enables developers to control the state of their applications from a single, centralised location. By utilising Redux, developers are able to create JavaScript programs that behave in a consistent manner. It is commonly used alongside React, as a state management technique, but may also be employed as a standalone JavaScript library.
  3. Node.JS

    Node.JS is a free, open source server environment which is based on the popular JavaScript programming language. It provides developers the ability to create scalable, efficient applications using a variety of JavaScript modules, simplifying the development process. By utilising libraries, developers can further enhance the efficiency and productivity of their applications. With Node.JS, building robust, feature-rich web applications is now easier than ever.
  4. Create Cross-Browser Code

    As a senior JavaScript developer, it is essential to ensure cross-browser compatibility in the code you write. This means that the website should be displayed in an identical way across different web browsers, such as Google Chrome, Mozilla Firefox, Apple Safari, and Opera, thus providing a consistent experience for the users regardless of their browser of choice.

How can I find opportunities for remote Sr. JavaScript developers?
