Web application developers are often looking for effective ways of managing state in their applications. State management is an essential part of developing JavaScript (JS) applications, especially React and React Native applications. MobX is one of the many tools available to React developers for state management.

React.js (React) is an open-source JavaScript library useful in building user interfaces. React is a library so our main focus for this article is installing a JavaScript environment and a Package Manager so that we can download and install libraries including React.

Node.js is a Javascript runtime built with fast deployments in mind. Both the client and server-side of the application are Javascript. It provides an asynchronous approach to serving up content, providing for extremely responsive applications. Node.js is cross-platform and installable on Linux, macOS, and Windows. This tutorial covers the installation of Node.js on a Windows Server.

What is Node.js?

Node.js is an open-source javascript runtime environment. It is memory efficient and is intentionally asynchronous. It is deployable on multiple platforms, including Windows, Mac OS X, and Linux, and is suited for rapid development. It’s event-driven architecture make it highly scalable and useful for intensive data-driven applications.

Node Version Manager, also known as NVM is used to control and manage multiple active versions of Node.js in one system. It is a command line utility and a bash script that allows programmers to shift between different versions of Node.js. They will be able to install any version using a single command and setting defaults using the command line utility.

Introduction

In this tutorial, we will discuss three of the most popular javascript frameworks: React, Angular, and Vue. We will look at the pros and cons of each, their usage statistics, discussions about which one to choose, and which one should be studied for future use. Because programming languages and frameworks are all tools in a developers tool belt, and each has its place. It is worth learning tools you find meaningful, useful to accomplish a task that’s not only convenient, but is suitable for specific tasks. Again, we should remind ourselves that because these changes occur rapidly, after a year and a half a year, the situation can radically change.

What is Yarn?

Yarn is a package management tool expressly designed to speed up the installation of packages from the npm registry by running operations in parallel to increase speed, improve reliability, and boost security. Yarn allows us better to automate the installation processes of npm software packages and is also advantageous when upgrading, making configuration changes, or removing npm packages. 

In our previous article on Selenium, we touched on the tools that the software provides for testing web applications. In this article, we will review the installation of these tools and some basic tests that can be run using the following tools. 

Introduction

Selenium is a suite of open-source testing tools for web apps that can be utilized across multiple platforms and browsers. Selenium is comprised of four different tools, each providing a different testing capability.

What is PhantomJS?

In this article, we will be discussing PhantomJS. PhantomJS is, in the simplest of terms, is a headless browser (headless, meaning without a GUI) that utilizes a javascript API. This function makes the browser very useful when used for:
