I'm applying for a job and I've been asked to develop a small web app using MEAN Stack with Angular 2+. Everything ok for the exception that I've been asked to use Gulp/Grunt also.
I did some digging and I found out that they are task runners and they were mostly used in AngularJS among other JS technologies, but I haven't found much information on Angular 2+.
So, my question is why should I use it in a MEAN stack web app and why using it will make my web app better? Doesn't Webpack do something similar already?
