Webix vs Ember.js

Webix is one of the most extensive UI component libraries, second only to Sencha ExtJS. Not only considering the number of widgets, but also the API methods for manipulating these widgets.

The most common way of working with webix is to create a JSON configuration of your view in JavaScript. When you use TypeScript, you get complete typechecking and intellisense in your IDE.

Even the most complicated GUIs are bug-free most of the time.

The webix Jet library adds all the required features for SPA development (routing, template loading, ...)

To get started is extremely simple. It has a low learning curve.

Regular updates and releases.

The company behind webix is really quick in answering any questions you have on their forum or via email.

Great design and icons pack.

Route handlers for the URLs can see a wide range of possible application states, asynchronous logic in the router makes sure of Promises. And implementing makes sense.

It batches bindings and DOM updates to increase performance; if similar tasks are added to a batch, the browser would only need to process them in one single go, as compared to re-computing for each task one at a time.

Ember's API are really easy to understand and work with. It has methods which allow you to harness complicated functionalities in an easy to understand way.

Promises represent an eventual state in asynchronous logic. Having promises everywhere (almost) means you could write simple and modular code, using almost any API that Ember provides.

The Ember Guides are well structured and very well written. The API documentation is also fantastic.

Ember is practically a complete full-stack front-end framework. It comes with it's own asset pipeline, router, services etc...

Ember follows the philosophy of "convention over configuration" meaning that it already has almost everything configured for you, so you just have to start coding and developing your project right away.

Ember comes with built-in routing capabilities. There's no need to install third-party plugins to be able to use routes.

Ember also has a debugging tool called Ember Inspector which is used for debugging the client side of your app.

Ember already defines the general application structure and organization for you. This was done to prevent developers from making mistakes which would needlessly over-complicate their application. While it's still possible to go out of these practices forced to developers by the Ember authors, you still have to go out of your way to force them.

Ember-CLI is a very useful tool. With just a couple of commands it scaffolds the code, installs dependencies and finally compiles everything itself. It's very useful to quickstart an Ember project.

Ember's preferred templating language is Handlebars. This is mainly because Handlebars is a logic-less templating language and Ember tries to keep it's logic outside the view.

Another reason why Ember benefits from Handlebars is mostly aesthetic as Handlebar's clean syntax makes for easier to read and understand templates.

Finally, Handlebars templates are compiled instead of interpreted, which means that they are much faster to load.

You can use any of jQuery’s features.

EmberJS provides with an extremely handy feature of advanced bindings. With this you can not only set the path to the binding value in your app but also set in which direction you want the changes to propagate to (oneway, single, multiple etc).

Having custom properties in your templates is itself a huge plus but having custom computed properties is an even greater benefit, since now you can code your custom function as a property and call it from your template. Hence rendering your page exactly according to your needs.

If you've used handlebars (Ember.js's templating is powered by HandleBars) helper tags in your code (like {{#each}}) you won't have to worry about updating your template each time you add/remove data from your page, Handlebars will auto update your template for you.

You build products instead of constantly configuring the stuff.

Glimmer 2, a new and very fast template rendering engine written in TypeScript, is fast due to smaller precompiled template sizes, faster parsing and initial render, and compiles at runtime to extremely efficient assembly-like append opcodes.

Most of Ember's components come from the Ember Object Model. It's the basis for views, controllers, models and even the framework itself. This means that the framework is extremely consistent since almost every component shares the same core functionalities and properties since they are all derived from the same object.

Ember provides a built-in data layer, which makes it super simple to keep the UI in sync with the back end.

Ember has a great core team and community of developers who are continually improving, updating and evolving the framework. The Ember team is always planning ahead and implementing the best of the latest technologies and practices, while ensuring backwards compatability.
