Can someone explain why the 'HttpModule' is crossed out?

I tried to follow the structure program of my instructor because I'm coding along with him. I must have missed something but I can't figure out what.

CodePudding user response：

So actually the Http module that you are using is officially deprecated and hence it is crossed out

You will have to use a newer HttpClientModule instead

It's an upgraded version of http from @angular/http module
