I cant see the benefit of mvc

MVC applies to more than just javascript. It's a popular architecture pattern that helps separate presentation, business logic, and data layers. This separation often makes it easier to manage application development and easier for multiple developers to work on it at once.

I'm not an expert yet, but I have a little experience with both.

What I can say is:

With JQuery, you have no data-binding that you have with Angular JS. This means that the vue and the model (the datas) are synchronized within AngularJS, which isn't the case with JQuery.

A good example in action of this behaviour might be seen here, play with the input you'll see the vue automatically updated:

Moreover, the example the teacher shows in the video is as well a good example. As you probably noticed, he could build the same list of people with less code using AngularJS. Without concatenating all the information that need to be displayed as you would do with JQuery.

At first you might think that's not that much a big advantage, but when you build a "big" app, that's really handy...

Depending on the project, just for this, I'm going to use more Angular now, there are as well some others good reasons to use that are beyond the scope of my knowledge at the moment...

I believe that the main benefit of using the MVC pattern is to have the so-called "Separation of concerns".

With MVC you are layering your app, thus making it easier to maintain and test. Though I believe it is possible to achieve it with the pure JavaScript coding, AngularJS makes it incredibly EASIER.

Frameworks = less code to do more.
