Django Rest Framwork and Angular

I am very new Django Rest Framework and Angular Js. What I wandering here is the best way to work with these two.

1. Django Rest and Angular js together (Most of tutorials showed me this)
2. Django Rest as backend and Angular js in frontend as 2 different projects

I am very confused, though I feel the 2nd approach is better. But still not sure. Can please anyone help me in this with pros and cons of both the approaches
