One of the basic question in developers mind that what is the difference between AngularJS and KnockoutJS, Which is better, and what is use. That is the subject of our article. For beginners if you are not familiar with AngularJS or KnockoutJS, I suggest you to go through Introduction of AngularJS and Introduction of KnockoutJS to get basic idea about these two frameworks. If you have confusion about KnockoutJS and jQuery read this article on KnockoutJS and Difference with jQuery. While Angular and Knockout are very different, they’re both excellent tools for building Single Page Applications, and the solutions ended up being quite similar.
Templating in AngularJS & KnockoutJS
AngularJS and KnockoutJS both provide DOM based templating. AngularJS only supports HTML as its templating mechanism. KnockoutJS uses HTML as its templating mechanism by default (which is where they both have DOM based templating ) , but KnockoutJS also supports other string based templating engines like Handlebars etc.
Unobtrusive in AngularJS & KnockoutJS
KnockoutJS helper functions "ko.dataFor(element) and ko.contextFor(element)" can be used in event handlers that are attached unobtrusively using something like jQuery’s bind or click. AngularJS doesn’t support Unobtrusive.
Context in AngularJS & KnockoutJS
In KnockoutJS, if we want to fatch data from a context that is in the parent of our current context, we need to access it using ‘$parent’. While In AngularJS, context’s inherit prototypically. So, to access something from the parent context, we don’t usually have to use $parent. We only need to use $parent if we have another variable with the same name defined in your current context as well.
Directives or Custom Bindings in AngularJS & KnockoutJS
AngularJS has directives. We can define custom elements, custom attributes, comments and classes. In KnockoutJS, Custom elements are a syntactical alternative to the component binding (and in fact, custom elements make use of a component binding behind the scenes). For example, you can create interactive components like grids, tabsets, and so on, in the form of custom bindings.
JQuery Dependency of AngularJS & KnockoutJS
AngularJS has its own version of JQuery called JQueryLite ( smaller jquery). If we include JQuery before AngularJS, it will use the JQuery that we loaded. While, KnockoutJS does not depend on JQuery or create its own version of it. But, having said that, KnockoutJS is a data-binding library. It does not have any opinions or implementations for doing Ajax or DOM querying. If you don’t include JQuery, you are free to do ajax and DOM manipulation either directly or with some other library.
Partitioning or creating new contexts AngularJS & KnockoutJS
AngularJS has a concept of controllers which allow you to create new contexts explicitly. AngularJS also implicitly creates context’s when using ng-repeat, ng-switch, ng-include etc. AngularJS’s controllers, services and its concept of DI make it extremely easy to partition and manage large applications. While KnockoutJS doesn’t allow you to create contexts explicitly (Unless you create custom bindings). KnockoutJS implicitly creates new contexts when using for-each etc.. It also shows that KnockoutJS has no opinion regarding the overall structure of your application.
Browser support for AngularJS & KnockoutJS
Both AngularJS and KnockoutJs are cross browser. AngularJS supports all new browsers and its support goes back till IE8. But, KnockoutJS supports till IE6.
