In this tutorial, I’m going to cover the first two ways as we haven’t covered services yet.

- Angular pipes are very simple, but useful functionality provided by Angular, and you will use them a lot.

The modules have their own application parts, which enable you to perform automated testing. It follows one file, one module principle where you don’t even need to remember the module loading order. At this point you should be set up and ready to build an Angular app, and have a basic understanding of how Angular works.

Also, I’m going to create two child routes with the router links of child a child B and give it a second router link. In this example, there are two additional child components child a and child b. As your application grows more complex, you may want to create routes that are relative to the component other than your route component. Now that you have defined your routes, you can add them to your application. We can use this approach to inject third party libraries in other modules that are available in the angular framework. Now we can reference our log service in our component and call our method from it should pass our message and as you can see it’s being executed.

TypeScript is a superset of JavaScript meaning that any valid JavaScript is valid TypeScript. TypeScript offers typing and a more concise syntax than plain JavaScript, which gives you a tool for creating more maintainable code and minimizing bugs.

- Also, let’s add submitted property, which will change depending on the state of the form and on submit method.
- Now the user should be able to submit this form after filling it, create a submit button on the bottom.
