Pros
Pro Uses Glimmer 2, a very fast template rendering engine
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.
Pro Continually evolving
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.
Pro Helps developers with keeping the structure of the application clean and simple
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.
Pro Debugging tool for almost every web browser
Ember also has a debugging tool called Ember Inspector which is used for debugging the client side of your app.
Pro Auto-updating templates
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.
Pro Uses a relatively clean and easy to understand templating engine
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.
Pro Increased performance because similar tasks are processed in one go
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.
Pro Clear and organized documentation
With so many amazing tools out there, a framework with a good documentation has become a distinguishing feature in choosing it for your next project. Forunately Ember.js does provide you with a very readable, extensive and easy-to-understand documentation.
Pro Easy to understand documentation
The Ember Guides are well structured and very well written. The API documentation is also fantastic.
