Since innovations constantly adapt and grow, staying competitive in the job market is one of the most difficult obstacles developers face today. If you want to advance in your career as a web or smartphone application development, learning Angular 4 is a worthy investment that will provide you with new work opportunities.
What exactly is Angular 4? Angular has increasingly developed into newer iterations in recent years, progressing from version 1.0 (AngularJS) to Angular 2 and Angular 4. Angular 4 is the most recent edition of Angular, having been released in March of this year. It’s a front-end web development framework built with TypeScript. Here are some details of why you should practice Angular 4 if you’re considering a profession that needs Angular expertise and how to learn it.
What is Angular 4?
Angular is a Google-developed and maintained open-source web development platform. It solves programming problems by combining declarative models, end-to-end tooling, dependency injection, and advanced best practices. It is revised on a regular basis to improve usability and developer efficiency.
Angular 4 is a JavaScript architecture for creating mobile applications and frameworks in JavaScript, HTML, and TypeScript (a JavaScript superset). Angular comes with built-in animation, http support, and materials, which include features like auto-complete, navigation, toolbar, and menus. The code is written in TypeScript, and is then translated into JavaScript and displayed in the browser.
Characteristics of Angular 4
Angular 4 is a complete rewrite of AngularJS, but it is an improvement on Angular 2. It is designed in a completely different way. The following are some of the characteristics that distinguish Angular 4 from previous Angular versions:
Typescript 2.1+ compatibility
The two recent versions of TypeScript, namely 2.1 and 2.2, are supported by Angular 4. This has improved the ngc rate and allowed for better type checking.
HTTP
Angular 4 supports the two most recent versions of TypeScript, respectively 2.1 and 2.2. The ngc rate has improved as a result, and form checking has improved as well.
Improved *nglf and *ngFor
You will use an if/else interface syntax in your models in Angular 4. You may also use a local variable to determine whether or not to unroll an observable.
A new View Engine that produces less code in Ahead of Time (AoT) mode
Unlike the ‘’Just in Time” mode, which compiles templates at runtime, the AoT mode compiles templates during the build, with the JS code produced afterward. This has a number of benefits, including the ability to find out if the template is wrong during the construction process. The disadvantage of AOT is that the created JS code is typically larger than the uncompiled HTML templates. When using AOT mode in Angular 4, the View Engine has been improved to reduce generated code by approximately 60%.
Animation package
Animations have been extracted from the Angular core (@angular/core) and packaged into a separate animation module in Angular 4. If you don’t need animations, you don’t need to use this extra coding in your development kits. Import the Browser Animations Module from @angular/platform-browser/animations to connect animations to the main NgModule.
Pipes
In Angular 4, a new title case pipe was added. Any word’s first letter is converted to uppercase using this pipe.
Router
Angular 4 uses ParamMap to display URL parameters instead of params or queryparams.
New SystemJS plugin
The “component-relative” paths in styleUrls and template URLs are dynamically converted to “absolute paths” by this plugin.
How to learn Angular 4?
Anything you’ve read up to this point has led to one central question: how does one become an Angular Developer? If you follow these moves, you’ll be well on the way to being an Angular Developer and starting a new career!
- Firstly, learn how to use JavaScript. Your Angular developer career will be built on the basis of JavaScript. This is fitting, given that Angular’s first edition was built on a base of JavaScript. Even if the newer Angular versions don’t depend on JavaScript as much as AngularJS, it’s always a useful ability to have. Learning JavaScript is easy, and there are numerous tools available to assist you.
- Secondly, learn how to use TypeScript. If you recall, we mentioned earlier in the article that knowing TypeScript was a useful ability to have. So, here we are, reminding you of the important point! You will pick up TypeScript in no time.
- Thirdly, Angular is a language that you can learn on your own. This is where you understand the framework’s ins and outs for the first time. After all, being an Angular Developer is difficult if you’ve never even seen the tool! There are a plethora of free tools available to help you master Angular on your own.
- Fourthly, attend lectures. Many Angular programming courses are accessible, either in a physical learning centre like a community college or university or via online education.
- Then, practice, practice, practice! Now is the time to put everything you’ve learned so far into practice by writing code. Trying to make someone with a new technique and only practicing by trial and error is the only way to gain experience with it.
- Lastly, join a group of people. There are several Angular-related online communities. You can read blogs, watch videos, and listen to podcasts as well. Joining an online community is a great way to make company friends, learn practical tips, and become more familiar with Angular best practices.
