Angular 2 is a modern application development framework. This is basically a structure that helps you create programs faster by providing a variety of services and objects that make things easier for application developers.

Angular 2 is a spectacular update of the previous version of the framework. We are really thinking about how applications should be built.

One of the main reasons for many of these changes is efficiency. Therefore, the angular 2 programs are 3-5 times faster than the previous version.

TL; DR

1. Application development framework;
2. Dramatic update from corner JS1;
3. Much faster operation;

What is different?

How is the Angular 2 different from the original version?

First, in the new version of AngularJS, everything revolves around something called a component. The ingredients are customized according to the AngularJS guidelines. They allow you to create features around custom labels. So, instead of adding the ngApp directive to the code section, simply rotate your own tags and then program the functionality of these tags yourself. This is very similar to the use of web components and is one of the best new features of the framework. The components are also as easy as customized according to the instructions of the AngularJS.

Second, because most of the components are processing components, there is really no need for drivers in the Angular 2.

Third, one of the main adjustments you should make is that in Angular 2 there is no more space, the template system is richer, which also means a stronger but more complex one.

 TL; DR

1. Focus on the components;
2. No more controllers;
3. No more scope;

AngularJS Programming

Now you can program AngularJS in different languages. This is one of the ways in which the angular 2 is essentially different because you can choose one of these three languages:

1. ES5: This is called regular JavaScript, also known as ECMAScript 5.
2. Dart – Google’s open source language.
3. TypeScript – Microsoft open source language. This is a JavaScript update that allows you to use all ES6 functions and adds some other important features.

The advantage of using the TypeScript type

Angular 2 was built with the TypeScript type, so it is important to learn to work with the TypeScript type. In addition, most of the documentation you will find for Angular 2 will also be written in TypeScript.

You can use any of the ES6 functions, you have access to classes. If you come to Angular 2 from ordinary JavaScript, you will have to get used to working with classes. They allow you to create a more specific approach to JavaScript. In TypeScript, the classes are very well organized and defined, so you will end up wanting to work with them in angular2.

The ES6 also has a rich template system, which is widely used in Angular 2, which makes it more attractive to create templates than the Angular 1. TypeScript also adds 2 important functions to the JS2 angles.

1. The first are types that allow you to specify the types of variables you use. Now, this is optional, but this is something that can help with troubleshooting, so it will be a good idea.

2. Another incredible feature of the TypeScript type is what we call the notes. Attachments are a way to add metadata to your code. Now, this is often used in Angular 2 to help you expand the components and do a lot of how to configure them. This is one of the features of AngularJS, which are very fun. Now, because the type and ES6 in current browsers are not compatible, you will need to use something to convert this code into normal JavaScript. This means that you will need to use a build tool such as Webpack or GulpJS to process the conversion.
