First and foremost, it improves your efficiency. Think of it as a shortcut of sorts: you have to write less code manually, as there are functions and patterns already pre-written and ready for you to use. Some components of a website do not need to be custom-made, therefore, you can just pre-built ones and build on them. Without the need to work on basic yet time-consuming tasks, you can concentrate on building unique features and perfecting specific details.
React: the number one
React is based on reusable components. To put it simply, these are blocks of code that can be classified as either classes or functions. Each component represents a specific part of a page, like a logo, a button, or an input box. The parameters they take are called props, which stands for properties. You can call your components in a certain order, place one inside the other, and create the look you like.
Angular: supported by Google
Vue.js: light and flexible
As Evan You worked in Google, he used Angular for a few projects. While he liked the possibilities it gave him, the overall system seemed too heavy for the simple tasks at hand. Therefore, it's only natural that the first thing most developers notice when trying the Vue.js framework he created and released in 2014 is how incredibly lightweight it is. With a file of just around 20 kilobytes in size, you can download and start using Vue.js in literal seconds.
Another strength the Vue.js has lies in its official command-line interface (CLI). It is tooling baseline that speeds the development up by offering a ton on plugins, presets, instant prototyping, and an interactive project scaffolding tool. We must add that the graphical user interface improves the user experience even further.
Aurelia: viva la web standards
Ember: stability and convention
The work in the Ember framework started in 2011, and the version 1.0 was released two years later. Instead of one company backing the project, Ember has many supporters that are usually also users of the framework – e.g., LinkedIn and Yahoo. Its main goal is to simplify web design – however, you can also use it for mobile and desktop applications.
Just like Aurelia, Ember is extensible. You can choose from a multitude of powerful add-ons, as well as create your own. Furthermore, it is highly scalable and can be used for huge projects. Apple Music, which has over 60 million subscribers worldwide, was actually built on Ember. If you want to see how, you can – there's a tool called Ember Inspector, which allows you to take a closer look at Ember projects online.
