General info

Template engines allow for easy and flexible UI building.
2.Supports computed properties
Knockout JS
Allows the use of functions as properties to compute properties of objects.
3.Extends HTML
Knockout JS
Some people see this as an advantage as it eliminates the overhead from another template language.
4.Published under MIT License
Knockout JS
The MIT License is a very permissive license which allows all uses, including business use, without warranty.
5.Has a stable public API
Knockout JS
The major version number is above 0. This means there will be no compatibility breaking API changes introduced by the development team.
6.Works well with more than just one template engine
Knockout JS
Other frameworks might be locked with a template engine you don’t like and there is nothing you can do about it.


1.number of plugins


Plugins offer an easy way to extend the functionality or integrate with other services. A high number of plugins may indicate an active community of users. Only official plugins are taken into account.
2.Has a popular plugin which supports input validation
Knockout JS
Plugin to help validate client input before it gets processed or sent to a server. While this does not replace server-side validation, it can vastly improve the user experience.

Libraries & Packages

1.Has an official, up-to-date entry in the npm package manager
Knockout JS
The node package manager can also be used for managing front end scripts.

Data binding

1.Has two-way databinding
Knockout JS
Models and views can be bound to update each other.
2.Supports one-way data binding
Knockout JS
Views can be bound to update automatically when an observable object changes.
3.Uses observables for data binding
Knockout JS
Models are observed for changes. This is a well known pattern. Can be more performant than dirty-checking in some cases.


1.minified file size without dependencies


Smaller file size means faster load times.
2.Templates can be pre-compiled on the server
Knockout JS
Supports a template engine that can be pre-rendered on the server. This possibly improves page speed, especially on devices with low computing power.


Less dependencies means less extra scripts to include, usually resulting in less development overhead and faster load times.
