Angular Practice Test 2023
Angular is a TypeScript-based open-source JavaScript framework. It is maintained by Google and is mostly used to create single-page applications. Angular has evident advantages as a framework, and it also provides a common structure for developers to work with. It allows users to construct huge applications that are easy to manage. The Angular team released the latest version, i.e., Angular 6, in April 2018. That is why we need to ensure that our Angular developers are updated with the latest version of this framework. However, it has already been widely used among web developers, so there is no need to worry about its popularity and credibility.
The term “Angular” is used to refer to multiple framework versions. Angular has seen multiple changes since its inception in 2009. While Angular 1, 2, and 3 are still the most widely used versions, versions 4 and 5 have also gained popularity among developers.
Angular is a web application framework that allows one to create single-page applications, which means that the front-end is fully dynamic, as it is created on demand by the user. Developers need not spend time dealing with development tasks rather than focusing on their application’s features. Furthermore, Angular helps in writing less code than other frameworks such as React or Vue. One of the most prominent aspects of this framework is that it offers a directive system for easily developing reusable functionality in an application. This framework includes pre-built components that can be utilized in various application topologies.

Angular Combobox
The Angular ComboBox component is a dropdown list with editable functionality that allows users to choose from a predetermined list of options. Filtering, item selections, grouping, and adding custom values to a dropdown list are all available with the Ignite UI for Angular ComboBox Component. Instead of the HTML select tag, it can be used and comes with several features out of the box, including data binding (both local and remote), filtering, grouping, custom templates, custom values, and more.
A Combobox is a type of input field with a dropdown menu of selections. Users can choose a value from a dropdown menu or type it into the input area. The data can be set directly in the HTML or pre-filled via AJAX. The data can be either in a JSON format or local to the component.
Angular get current route
An Angular router is a useful tool for navigating through an application. It’s a must for developing single-page applications. The router is used to navigate between routes, and it also contains the data for the URLs that are being navigated. For example, a URL can be specified with a route and then matched with the defined URL. So, if any route matches the URL, it will be matched with the defined route.Â
The strings identify routes in the URL template, referring to named routes or parameters. The router uses the navigation events to do navigation, and when it’s in a new state, it calls a navigation complete function which can be used to clean up any effects of the previous view.
React vs Flutter vs Angular
React is built on the ES6 + JavaScript language and JSX, a JavaScript grammar extension that allows you to mirror JavaScript code in HTML. Because developers enjoy writing code in JavaScript, mastering React is simple for any JavaScript developer. Fluid and progressive concepts, a virtual DOM, lazy loading, and two-way data binding are just some of the features and benefits of this framework.
Flutter is a framework made for developing applications with iOS or Android. Because of the similarity between these two platforms, the benefits of Flutter are more noticeable when developing for both mobile platforms. The framework is built on Dart, a programming language and code generator developed by Google with assistance from Facebook. It is an open-source app development tool by Google that provides an environment for rapid app development. This framework also includes extensions such as reactive forms, gesture updates from the main screen, and swapping them out on the fly. Moreover, CSS animations and programmatic layouts are possible with this tool.
Angular uses TypeScript, a superset of JS designed for larger projects. In comparison to JavaScript, TypeScript is rather small. It makes it easy to navigate, and the refactoring process goes more smoothly. Angular is a rewriting of AngularJS, a JavaScript framework, that has been improved to make TypeScript usage more simple. Developers need to know that the TypeScript language has a static type system, which means that it is an automated unit-testing framework that allows for type checking.
The TypeScript Compiler, a part of the Angular core framework, will be used to compile all the JavaScript code when an Angular application is loaded. It also takes care of compiling Angular code and upgrading dependent JavaScript libraries later on. Regular JavaScript typing rules typed checkers, and even static analysis tools can all be used to configure the TypeScript compiler.
Next.js for Angular
Next.js is a framework designed to solve the large problems with Angular’s internal routing and routing logic. The framework has been designed to be simple, manageable, and fast. Prezi developed next. Some of the benefits of this framework include a completely rebuilt routing system and lightweight abstractions for data management, state management, and other common functionalities provided by Angular.
Next includes the ability to host anywhere on the web with support for both HTTP/2 and WebSockets out of the box and Active Server Request (ASR). When combined with Next’s routing system, Router’s two-way data binding methods give developers simple debugging tools to confirm that their routes are running properly.
Angular generate component in subfolder
We can use the ng produce component command to create components in a subdirectory or a specific folder. It will generate the components and their dependencies, templates, and styles. All outputs can be found under the subfolder.
Using this command saves developers a lot of time in the development process; instead of traveling back and forth between a folder for each necessary component for an application, Angular allows us to create components altogether instead of creating them separately from scratch.
Angular routerlink not working
Sometimes developers have a problem with the Angular router link not working. This can happen when a request is made to a route not available on the currently loaded page. We need to use a special flag in the router outlet to fix this problem. The two parameters of this route are “query” and “null.” The query parameter contains the URL that our current page should match, and the null parameter is used for new routes that do not exist within the application.
Angular API keys
Angular provides an API key that allows developers to control the entire application. When a developer deploys the application, they can be sure that no one can modify it. Only the developer who has added this API key will be able to modify it. The API key can be used to send push notifications and other customizations. Ensure that the API key is provided only once in the application’s directory.
Secured API Keys are important when you wish to limit your search to certain indices. On the backend, such keys must be produced. Otherwise, users can change the key’s limits by editing the front-end code.
Angular hover CSS
Hover effects are one of the most popular patterns used on websites. It is also a viable alternative to websites that do not have any hover effects. Although the hover effect is an old trend, its popularity has been enhanced with frameworks such as Angular and jQuery. Angular uses the ngAnimate library to provide better support for using CSS3 transitions and animations. It can be used to create simple animations and advanced interactions when necessary.
Angular ng-if multiple conditions
The ngIf directive in AngularJS (https://angular.io/features) is a powerful tool for dynamically showing and hiding HTML information. It can also use an expression to show or hide content. We can use the ng-if directive with several conditions.
To determine the trustworthiness of a *ngIf statement, we can employ numerous conditions with the logical operator AND (&&). The element will be added to the DOM if all conditions are met. We can also use the OR operator (||) with *ngIf to ensure that we show the element.
Angular font
All of the components in AngularJS Material use the Roboto font. The Roboto typeface will not be loaded by AngularJS Material by default. The developer must load all fonts used in the application. The developer can specify the font in the AngularJS Material theme or upload a custom font using the ngMaterialModule’s @font-face directive.
The same fonts are used in AngularJS Material UI.
Angular Onpush
The OnPush strategy modifies Angular’s change detection behavior in a similar approach to detaching a component. Change detection is no longer performed automatically for all components. Instead, Angular listens for specific modifications and only detects them on a subtree for that component. This strategy enables faster and more efficient performance, but it also shifts some responsibility from Angular to the developer.
Angular prevent back button
We use History to prevent browsing back navigation. web api pushState() We set history as soon as the user lands on the component where we wish to disable back navigation. pushState(“, null).
