How are JavaScript frameworks created

The top 10 frameworks and what tech recruiters need to know about them

Since programming and the development of applications are becoming more and more sophisticated and complex, developers are expected to do much more than just master the programming languages. You need to understand the frameworks that make it easy to build applications in these languages.

A framework is a set of tools and functions that serve as a platform for creating a full-fledged application. There are a few tasks that appear in every app. These are, for example: input, display rendering and error handling. Frameworks handle such functions so that developers can focus on solving the problems associated with their specific domain. However, a framework is a broad term - different frameworks do different things.

As a tech recruiter, you should understand what frameworks are and which are the most common. If you are already familiar with these terms, you probably know frameworks by the term front-end JavaScript frameworks. You will see that there are frameworks in many programming languages ​​that simplify the development process.

You can compare other technologies in the free tool. All technologies tagged on Stack Overflow are included here.

In the graphic above you can see the change in the use of tags in Stack Overflow for the ten frameworks mentioned below over approximately ten years. The popularity of frameworks rises and falls as new frameworks are created and old frameworks are replaced with new ones.

Today we introduce ten of the current and popular frameworks.


Facebook first launched React in 2013. Since then, it has rapidly grown in popularity. It is built from JavaScript and designed as a modular basis for reusable UI components. In fact, React isn't really a framework, but it has a huge ecosystem of helper libraries that offer great functionality. There is also React-Native, which compiles to native iOS and Android code so that app developers no longer have to create three separate front-end code bases.


Angular (formerly AngularJS) comes from a Google project. In contrast to React, it offers developers a complete framework as a first-party library. The current version uses TypeScript (although JavaScript and Dart are supported), which is a parent group of JavaScript. In the past only JavaScript was supported. In order to meet the requirements of the users, the language from version 2 was completely rebuilt. Angular is incredibly popular because its all-in-one setup and rigorous syntax checking provide developers with plenty of support tools and it helps keep code consistent. With everything in one package, there is no need to involve the third party code with its potential vulnerabilities and legal pitfalls. However, this can be a major disadvantage for some applications, as the entire Angular framework can be unnecessary ballast if you don't need all of the functions. Even with the redesign of the second version, Angular remains one of the most popular front-end frameworks and, thanks to Angular Universal, is also gaining ground in back-end applications.


Django is a fully Python-based web framework originally developed in 2003 by web programmers for a newspaper in Kansas. Because it is free, it has been very popular. Thanks to its modular design and sophisticated component system, it simplifies a lot of common web development tasks - including serialization of data, caching and authentication. It covers the whole area of ​​web development, but can only be used as a backend.


Laravel is a free, open source PHP-based web framework that was developed about eight years ago. It was originally based on Symfony and was created to fill in the gaps in functionality that Taylor Otwell found in the CodeIgniter Framework. It offers expanded support for things like authentication, interaction with relational databases, and dependency management. With a modular packaging system and many additional tools and applications that support the system, Laravel offers a complete stack framework that makes development noticeably easier.

Ruby on Rails

As one of the early backend frameworks, Ruby on Rails influenced much of the web development technologies that followed. Due to its early appearance, Ruby enabled a large part of the standard technologies that create Web HTTP, JSON, CSS, JavaScript, etc. - and builds on the software development philosophy of CoC (Convention over Configuration) and DRY (Don't repeat yourself ) on. This means that Ruby tries to define data models and application logic only in one place and only if this definition deviates from the norm.


Depending on how much the developer wants to take on, Vue.js can serve as a simple JavaScript library or a full front-end framework. This phased adoption approach, which was designed in response to the high demands of AngularJS, means that applications that only need small parts of Vue's functionality do not need to slow down their application by importing. For those who want it, Vue and its tools can form the backbone of complex web applications.


While most of the frameworks discussed here are built on web-first programming languages, Spring is a framework for Java that can be used as part of a web application or a native desktop or mobile application. It manages low-level operations for complex applications such as dependency injection, database interactions and transaction management and at the same time facilitates the modularization of the code with so-called aspect-oriented programming. While Spring can be used with any Java application, it is often included in backend web applications.


Express (or Express.js) works as a web framework for Node.js, which is itself a so-called runtime environment for JavaScript. That is, it runs JavaScript outside of a browser. It's completely free and serves as the backend part of the standard MEAN stack. Like many modern frameworks, it has a small core library, with a large part of the functionality being taken over by plugins. This flexibility and versatility has resulted in several frameworks building on top of Express, which is why it is not ranked higher in the graphic above.


Microsoft created ASP.NET with open source support to create the successor to Active Server Pages (.asp). Instead of being based on a single language, ASP.NET can run on any language that uses .NET. So it's a strong back-end framework for companies that use a Microsoft stack (like us). Because it's made up of compiled languages, it's fast and scalable.


You might think the free and open source JavaScript framework space is already saturated, but Meteor is making the leaderboards. With Meteor, real-time applications can be easily written, a full-stack framework can be easily represented and the reuse of code simplifies mobile versions. It enables fast prototyping and less code for an application, while also making it easy to propagate code changes to all clients. Meteor's popularity may be short-lived as frameworks come and go quickly these days.

There are tons of other frameworks out there as well as popular non-framework libraries (yes, we think of you jQuery!) So please don't see this list as exhaustive. But it should give you a good overview so that you can talk a little more on an equal footing with candidates and HR managers in IT.
