Efficiency — projects that used to take months and hundreds of lines of code now can be achieved much faster with well-structured prebuilt patterns and functions.
Cost — most frameworks are open source and free. Since they help programmers to build custom solutions faster, the ultimate price for web app will be lower.
After a long-awaited release of Angular back in 2016, its popularity has touched new heights, though AngularJS will hold off on giving ground in 2018.
Angular.js is often referred to as an MVW (Model-View-Whatever) framework and among the top benefits, for startups and mid-sized companies, people name: quick code production, easy testing of any app part and two-way data binding (changes in the backend are immediately reflected on the UI). Since release its ecosystem has gone beyond imagination. As for now, it is reasonably called the most used JS framework for SPAs (Single-Page Applications) development and it boasts the largest community of developers.
Both Angular-s are a better option for enterprise-based applications or for strict programming environments with high standards for code readability.
We’ve already made React and Angular comparison, despite the fact that it is more of a library than a JS framework. It stands behind user interfaces of Facebook and Instagram, showing its efficiency within dynamic high-traffic applications.
It is rightly considered the fastest growing JS framework: as of today, there are about 1,000 contributors on Github. In MVC (Model-View-Controller) pattern React.js acts as “V” and can be smoothly integrated with any architecture. Due to the usage of virtual DOM it provides a great performance boost, comparing to Angular 1.x. In addition to that, React components can be created and re-used among applications or even transferred for public use.
Despite the fact that React has a higher learning curve, it makes app development straightforward and easy-to-understand. Furthermore it can be a perfect fit for complex, high-load and awesome software solutions.
Vue 2.0 was also introduced in 2016 and it took the best from Ember, React and Angular, putting all that into a handy package. It is proved to be faster and leaner, comparing to React and Angular 2.0.
Going deeper, Vue.js offers two-way data binding (seen in AngularJS), server-side rendering (like in Angular2 and ReactJS), Vue-cli (scaffolding tool for quick start) and optional JSX support. Its founder states that Vue 2 is one of the fastest frameworks all in all.
Vue.js is a better choice for quick development of cross-platform solutions. It can become a firm basis for high-end single page applications (SPAs) and beneficial solution to those cases, when performance is put ahead of good code organization or app structure.
Ember features two-way data binding, like Angular.js, keeping both view and model in sync for all the time. Applying Fastboot.js module it ensures prompt server-side rendering of DOM, improving performance of complex UIs.
Emberjs is commonly usable for complex feature-rich web applications and website. Among the top users are Chipotle, Blue Apron, Nordstrom, Kickstarter, LinkedIn, Netflix and many others. Moreover it has an easier learning curve and there are oceans of tutorials and guide available online.
MeteorJS covers all the phases of software development cycle and takes care of such glooming processes as linking, files concatenation and others. It is of current usage in real-time application development for business companies like Mazda, IKEA, Honeywell and many others.
