Angular 6 Interview Questions: Angular 6 is compatible with Angular Elements. We’ll be able to use our Angular Components in other environments thanks to Angular elements. The latest tooling enhancements are particularly useful for making it easier to update, upgrade, and introduce additional libraries to apps.
Are you thinking about enhancing your programming skills? It’s never late than never, so, while considering a career as a Software Engineer, you can get started by studying the Angular 6 work interview questions and answers, you will be able to attend the interview effectively as a Net Developer, Web Developer, and so forth.
Shall we get started? Following are the 11 most common Angular 6 interview questions that you may face in an interview, let’s take a look-
What is the use of Codelyzer in Angular 6?
Ans- Codelyzer is a method for analyzing the static code of Angular TypeScript projects. This tool sits on top of TSLint and verifies that the Angular TypeScript projects adhere to the linting laws. It has over 50 rules for Angular projects to review. You may use the npm package manager to apply this tool to your project. This tool can be used to operate a static code analyzer on web applications, native scripts, and other types of code.
Explain in detail the reason for using the renderer method in Angular JS, whereas we can easily able to handle the same by using native element methods. Was there any facility for using the same? Explain.
Ans- For rendering information, Angular will presume that only one platform and browser are being used. If Angular is going to use any of the native elements of the Angular DOM, those components can only be used in the same DOM context. In Angular 6, a new class called Render2 has been introduced, which aids in the preparation of native elements such as web component elements so that they can be utilized anywhere without relying on the DOM.
Ans- A tiny piece of information sent from a website and saved on the user’s device by their web browsers while they are surfing is known as a cookie.
What is fork-join in angular 6?
Ans- When you’re about to wait for several HTTP requests to be resolved, the fork-join operator is employed. It creates a single observable array from all of the observables returned by each HTTP call and finally, the measurable array is returned.
What do you mean by Angular 6 elements?
Ans- Angular elements allow users to build custom elements without relying on a structure. These elements can be used in simple web projects, but they contain Angular functionality.
Tell me the use of subscribing in Angular 6?
Ans- Subscribe in Angular 6 is a mechanism that is useful for streaming data asynchronously and synchronously to a variety of machines that have subscribed.
Define host listener in Angular?
Ans- In Angular 6, the host listener decorator determines a DOM event to listen for and also defines a handler procedure to operate if and when that situation happens. When an occurrence happens, the host listener influence is utilized to override the handler mechanism.
Explain in detail the compiler using by Angular, called AOT (Ahead of Time)?
Ans- AOT is an abbreviation for “ahead of time.” Angular uses it to precompile all of the angular elements and usable templates during the upgrade process. AOT has always operated in an angular-based program.
Define the use of Async pipe in Angular 6.
Ans- In Angular 6, an async pipe is a form of corrupted pipe that either wait for a guarantee to settle or displays the data to a visible showing the emitted properties.
What is the use of Codelyzer in Angular 6?
Ans- Codelyzer is a method for analyzing the static code of Angular TypeScript applications. This tool is present on top of TSLint and verifies that the Angular TypeScript projects adhere to the linting laws. It has around 50 rules for Angular projects to review. You may use the npm package manager to apply this tool to your task. This tool can be applied to operate a static code analyzer on web applications, native scripts, and other types of code.
Tell me the use of router outlet in Angular 6?
Ans- The usage of a router-outlet is that it serves as a placeholder for multiple elements that are animatedly loaded depending on the latest route condition and enabled feature.
