How do I get the most out of an academic economics journal?

Hi, I’m currently 2nd year undergraduate student who will be declaring a dual major in economics and math in the fall (beginning of my 3rd year). I want to start getting into the literature base, as I want to continue my education in economics to grad school.

I understand that journals are important for academia; however, I am not sure the role they serve, or how I can take advantage of them as a tool for learning the best. I wanted to get some clarification on these topics as well as some recommendations for journals or articles of note.

Thank you!
