Q2. What is Angular 8?

SUGGESTED ANSWER

“Angular 8 is a JavaScript front-end web framework used to create dynamic web applications. It is open-source and predominately maintained by Google. The “8” refers to the version number of Angular. Its purpose is to provide an easy-to-use framework and platform to create web-based applications that can be cross-platform. Angular 8 was developed by the same team behind AngularJS, but it is a complete rewrite. Some powerful features to note in Angular 8 are the end-to-end tooling, and dependency injection, both of which make the development process simpler. “

WHAT ARE THE MAIN FEATURES OF ANGULAR 8?

This interview question is likely to feature during your Angular 8 interview. Here’s the perfect answer to help you:

“With the arrival of Angular 8, there were some exciting new features that I particularly welcomed as many of them are there to ensure a smoother development process that performs better. For example, Angular 8 introduced improved ngUpgrade and dynamic import syntax support, instead of being restricted to lazy-loaded modules. One of the biggest upgrades was the introduction of the web worker class. This allows the main thread to free up to update the user interface and enabling CPU intensive operations can be handled in the background thread instead. In addition, other big changes are the new build system Bazel and the new complier, Ivy Rendering Engine, enabling quicker and more efficient CLI application building. TypeScript 4.3 is needed for all Angular 8 applications to run now.”

WHAT QUESTIONS ARE ASKED IN AN ANGULAR 8 INTERVIEW?

The 50 Angular 8 interview questions listed on this page are the ones that have featured more prominently during the last 12 months from all job interviews where Angular 8 competency is required as part of the job description.
