Often when we are using JavaScript techniques inside Angular, we almost forget about the framework’s features. Let's utilize them.

One of the interesting topics in web development is DOM manipulations. There are many ways to manipulate the DOM in Angular. Let's use them instead of straight forward JavaScript approaches.

Usually, there are two concepts in DOM Manipulations.

1. Modifying DOM Elements.
2. Modifying DOM Structure.

Modifying DOM Elements:
