2. Angularjs • The JavaScript AngularJS is a very powerful framework for front-end web development. It is used in projects called Single Page Applications (SPA). It adds more attributes to HTML DOM and makes it more sensitive to user actions. AngularJS is free and open source, and it is used by developers all over the world by the thousands.

3. Web development using Angular AngularJS is a web application framework that is free to use. It was first made by MiskoHevery and Adam Abrons in 2009. Google now takes care of it. It is currently at version 1.2.21. Some key benefits of website development using Angular are: • AngularJS is a good framework for building Rich Internet Applications (RIAs) (RIA). • Developers can use AngularJS to write JavaScript client-side applications in a clean Model View Controller (MVC) way. • Applications made with AngularJS work in all browsers. AngularJS handles JavaScript code in a way that works for each browser automatically. • Overall, AngularJS is a framework for making web apps that are large, fast, and easy to maintain.

4. 5 Steps to Optimize Your Web Development Process with Angular • Change detection • One of the most common features app developers use in the web development process with Angular is change detection. It can mostly tell when the user’s data has been changed or altered by updating the DOM to show the changes. • Here, framework parts can find the information they need to get information from their parent parts. When an async event happens, Angular looks at the component tree and stores any data that is different from what it was before. • For the app to work well, the strict equality operator is used to look for any differences. This operator checks to see if the inputs or components of the branch have changed. And, as a result, a new amount of memory is given to the current values of the input.

5. 5 Steps to Optimize Your Web Development Process with Angular • Lazy loading • One of the best ways to use web development angular is to use Lazy Loading. Using Lazy Loading can help you improve your application’s speed and efficiency. Lazy Loading is a built-in feature that lets JavaScript load the component asynchronously whenever that route is hit. It divides the whole app into different bundles to control how fast it runs. So, every component that has to do with the active route will be loaded. • Lazy Loading is only used at the beginning of an Angular app. Once the user opens the app and starts to navigate, it will load right away.

6. 5 Steps to Optimize Your Web Development Process with Angular • Ahead of time compilation • AOT stands for “ahead of time compilation mode.” During this phase, the angular compiler creates the ngfactory files when a build package is made. Instead of doing this during the browsing phase, it does it ahead of time. If we compare this to JIT mode, we can save a few seconds and won’t have to send”@angular/compiler” to the browser at all. In the end, that will speed up the first load. (You can’t use AOT mode if you load your components on the fly; in that case, you must use JITCompiler.) If you want to see the AOT version of files locally, run the “ngc” command in the command line. This will create *.ngfactory.js files.

7. 5 Steps to Optimize Your Web Development Process with Angular • Use track by • “*ngFor” directive lets you use the same template for each item in a collection. Imagine that you are getting a list of employees and putting all of their information on the page. If a user adds a new employee from the modal on that page, we re-fetch the list from the server and put the new value in the list variable. That makes that ‘ngFor’ directive get re-rendered. Most of the time, we only accept adding a new item to a list when a new collection is re-fetched. It seems like ngFor is re-rendering the DOM without reason.

8. 5 Steps to Optimize Your Web Development Process with Angular • Scaled images • With Serve Scaled Images, you can make your Angular web development faster. It is a way to change the size of images on your website, which makes the site run better. Even though large images can be shrunk down to a fixed size, this will take up more space and slow down the website. Developers must make sure that the uploaded images are the same size as the HTML images on the website so that angular works well and the website doesn’t slow down.

9. Conclusion • Web development with Angular is one of the most popular ways that developers build web applications. Using this open-source framework one can make great apps that make the user experience better.
