Don’t worry, just read the 50 most important Angular JS interview questions we’ve outlined in this post.
It’ll help you sense the level of the questions asked in interviews and thus increase your probability of selection.
But don’t forget that success not only depends on your technical skills but your behavior matters too. Angular JS works fine with the latest versions of Safari, Chrome, Firefox, Opera 15 , and IE9 (Internet Explorer).
Hence, if you want to be a cut above the rest, then prepare in advance, practice more, and perform well. It also supports various mobile browsers like Android, Chrome Mobile, i OS Safari, and Opera Mobile.
Whereas a singleton enabled class will create the object first time and return the same object onwards. Scope object has access to both View and controller.
Thus it works as a medium of communication between both of them. We can use it to access model data of the controller. Using root scope we can set the value in one controller and read it from the other controller. Every Angular JS application consists of one root scope but may have several child scopes.
Similar to DOM, they also create a hierarchical structure. Single-Page Applications (SPAs) are web applications that fit on a single HTML page.
It dynamically updates the web page as the user performs actions on the app.
An app can have only one $root Scope which will be shared among all its components. These new scopes get added as children of their parent scope.
Thus the user navigates to different parts of the application quickly as it happens without refreshing the whole page.
Key Characteristics of Single-Page Applications are as follows. However, the “scope” will be used to create a link function for the custom directive.
For example, a controller may be defined as (let’s define $scope as the first parameter in this case): Thus, Angular JS does not care for the position of “$scope” in both the cases.
It uses the argument name to retrieve an object out of the dependency injection container.
