A week before I started backend and api certificate course on free code camp and complete till express. When I started mongoDB and mongoose the version in gitpod is old one and it's not comparable with the node js latest. What should I do is there no other way i which I can do all exercises and project in all latest versions of express and mongoose. I don't wanna go and do projects in old versions so can anyone help me with my situation.
