1. Angular JS
- Dynamic and Fast – Allows us to deliver rich, dynamic, and fast-loading content that mimics desktop applications.
- Single Page Applications – These load the full site content within a single page using an index.html file such that once the page is loaded, you can update a section within that page by clicking on them.
- Popularity – AngularJS is the most popular client-side framework.
- Less Coding – With AngularJS framework, you need fewer lines of code.
- Steep Learning Curve – Learning Angular is quite tough, as it has a lot of details packed in on how to properly use the framework.
- New Terms and Concepts – Terms like “transclusions”, “dirty-checking” or “factories” are intimidating and unfamiliar for new developers to learn.
- Many Ways To Do Things – Very often, there is more than one way to get something done with AngularJS. This can lead to confusion about the best way to do something.
Angular JS is best suited for rich, dynamic web applications. It also supports Model View Controller (MVC) programming structure.

2. React JS
- Dynamic Web Apps – React helps in the easy creation of dynamic web applications.
- Virtual DOM –When the state of an object changes, Virtual DOM changes only that object in the real DOM which makes things faster.
- One-Way Data Binding – React involves a unidirectional flow of data. This keeps everything modular and fast.
- Reusable data components – React uses reusable data components. This helps decrease the development time.
- Server-Side Rendering – React JS applications are rendered on the server rather than the browser.
- Component Reuse – Uses the so-called components which make it possible to split the user interface into independent, reusable pieces.
- Virtual DOM – Just like the actual DOM, the Virtual DOM represents all elements and their attributes as a node tree.
- Thriving Community – React has an open-source library and Independent developers from all over the world who constantly propose new features and even fix bugs.
- High Pace of Development – React is in a constant state of flux, with new features being introduced on a regular basis, which beginners find difficult to grab.
- Lack of Conventions – React is a relatively young library that is very actively developed by Facebook and contributors from around the world. Thus, there are very few established conventions.
React JS is best suited for making reusable UI components and for making big website applications that do not need reloading of the page.

- Watchers – This is used for data that changes frequently. Such as form input elements.
- Incrementally Adaptable – Vue focuses on the view layer on making UI better for the user.
- Server-side Rendering – This helps the page work faster on the client’s side.
- Approachable and Performant – It allows you to create a more maintainable and testable codebase.
- Smaller Size – Vue is only 18kB which means that it is extremely fast.
- Reactive – This is due to Vue’s data binding and Virtual DOM features, which help with real-time updates.
- Low Popularity – It can be hard to find an answer if you’re stuck, as the majority of Vue users aren’t English speakers.
- Lack of Plugins – There is a dearth of important plugins such as Google Maps, that can have an impact on the project length.
- Too Flexible – In complex projects, where more developers are involved, Vue’s over flexibility can be a problem.
Vue.JS is best suited for single-page applications, to program widgets, and to create more complex front end apps.

Ember is a framework designed keeping large web applications in mind, although it can be applied to smaller projects as well.
Ember is opinionated – meaning that there are strict guidelines laid out by the developers on how the pieces of the framework should be used. Here, URLs are the backbone of the app.
- Convention Over Configuration – Ember will generate large blocks of code for you. Some of this code can be configured to achieve specific app behaviour. Ember does this by using a naming scheme.
- Model–view–view model – Basis the MVVM pattern, developers can make scalable single-page applications using Ember.
- Rapid Release Cycle – Ember is known for short and frequent release cycles. This allows Ember to implement fixes and new ideas.

- One Terminal Command – Ember has one terminal command which helps to easily add a lot of extensions to the app.
- Built-in Testing Tools – The standard Ember-cli application is supplied with QUnit.
- Active Community – This provides constant support and helps solve problems.
- Bound by REST standards – If you need to fetch data from API that is not bound by REST standards, you might have to write your own Ajax requests using jQuery middleware.
- Tight Coupling – Ember.js is tightly coupled with jQuery.
- Steep Learning Curve – It is tough to learn Ember due to its constant and fast updates.
- Less Room for Customization – If you want to be able to customize a project, it’s best not to use Ember as it can be very limiting in that aspect.
Ember.js is best suited for startups who want fast delivery for a large app.

5. Meteor JS
Meteor does not need your Ajax Code and neither requires you to manipulate the DOM. It’s written using Node.js and is an open-source isomorphic framework.
- Latency Handling – In the meteor, the response is shown immediately. By the time it returns from the server with an updated response, those changes will be updated too.
- Smart Packages – These speed up development as they increase the chances of readymade packages in case you need to develop something. You can find these in libraries.
- Self-Contained App Bundles – The whole application to be created using meteor can be made into a single, compressed file and can be deployed anywhere where Nodejs and MongoDB are present.
- Real-Time Web Development – Data in the templates gets updated automatically, as soon as the changes are made.
- Develop With A Single Language – The development process is highly simplified with the frontend, backend, and database all rolled into one.
- Avail Smart Packages – Readymade packages are available in case you need to develop something.
- Lacks Server Side Rendering – This is very important for Search Engine Optimization.
- MongoDB Support – MongoDB is known for issues with data integrity and yet this is the only official solution for backend options.
- Absence of Native Widget Library – While this is missing, is it compensated by various client libraries.
- High Dependence on Internet Connection – If you have a weak internet connection, you may lose synchronicity between the frontend and backend.
- Lacks Inbuilt PWA Support – This causes slow loading of the first page.
Meteor JS is suited for cross-platform code (Android, iOS, Web).

- View Layer Paradigm – This is designed to be declarative, rather than procedural where developers write custom code at the view-level.
- Lightweight – It is 7kb gzipped, with no dependencies.
- Small Learning Curve – It’s about 2000 lines of code. A developer simply needs to read the documentation and can figure it out pretty easily.
- Blazingly Fast – It has Virtual DOM diffing and compatible templates.
- No Database Integration – It only supports MongoDB and cannot be used if you need to include NoSQL database support.
Mithril JS is useful for developing web applications with its full-stack solutions.

- Asynchronous APIs – In Node, the server calls on the API one at a time. While moving to the next one, it uses a mechanism to generate a response from the API called earlier.
- Single-threaded – Node.js follows a single-threaded model.
- No Buffering – Node gets the data in big pieces of data which brings down the processing time significantly.
- Easy to Learn – It can be used for prototyping and agile development.
- Highly Scalable – Node can be used for building super-fast and highly scalable services. It is used in production by companies like PayPal, Uber, Netflix, and Walmart.
- Lesser Code – At PayPal, it was found that the Node application was built twice as fast with fewer people, with 33% fewer lines of code and 40% fewer files.
- Largest Ecosystem of Open-Source Libraries – For any features or building block you want to add to your applications, there is always some free library out there that you can use. So you don’t have to build from scratch.
- CPU Bottleneck – Node is single-threaded by nature. Whenever there is a heavy computation request, Node JS would set up a block on other requests on the thread, causing an overall delay.
- Immature Tools – NPM registry seems to be quantity, not quality driven. While core products are stable, the rest of the NPM registry is poorly structured and badly documented.
- Few Experienced Developers – There is a lack of experienced JS developers that work with backends.
Node.js is suitable for backend services or APIs with power client applications – such a web app, running in a web browser, or a mobile app running on a mobile device. It is used for highly-scalable, data-intensive, and real-time apps.

- Simple to Use – Polymer is very streamlined and simpler to use.
- Growing Library – It has a growing open-source library to pull custom elements out of. This makes development quick and easy.
- Lack of Guidance – There isn’t much documentation for Polymer at the moment.
- Misleading Error Reporting – When you get an error, it doesn’t really tell you why and neither is Polymer very intuitive to figure it out.
- Slower for Large Applications – Since everything is done on the browser side, every time you refresh the page, everything has to be reloaded again which takes time if your application is complex.
- No Server Side Rendering – The user has to wait for the app to fully load before interacting.
Polymer is suitable for highly customisable, complex, and scalable web applications.

Download link for Svelte.js – https://svelte.dev/
- Read-only State – The only way to change the state is to send out an action.
- Pure Reducers – There are multiple reducers that modify the piece of data off the store. This is done in an immutable way.
- Avoids Bugs – It changes the flux framework and helps you avoid complicated bugs.
- Easy to learn – This is similar to writing HTML with interpolation.
- Total Separation State – There is a complete separation of state and presentation.
- Never Think About Re-rendering – You don’t have to be concerned about whether something has been previously rendered, or whether it’s the first time.
