A great feature that Angular has is to dynamically load component in a Higher Order Component by using the ComponentFactoryResolver. Apart from this, we can also lazy load a component using ES6 import.
Did you know that a wrong SCSS usage can increase the bundle size of your Angular application? And you know what this issue is, right? A performance issue!! The bigger the bundle size the more time the browser requires to download all the files and the more time it takes to paint the page.
A side note here: The CSS is render blocking which means that the browser won't render anything until all the CSS is downloaded and the CSSOM is constructed.
Having this in mind, we have to take extra care of our CSS. Don't we? :)

Let's assume a simple story which will help us understand this. (well OK, I know that its not the best example you've ever read)
A father asks his son to go and buy a newspaper. The father is awaiting for the newspaper and will start reading it when his son returns back. On the other hand, the father knows that his son, who loves playing out in the yard, has some possibilities to fall down and start crying. In this case he won't read his newspaper and he will have to care of his son.
There are two cases in the story; the father will read the newspaper. The father won't read the newspaper.
