I love podcasts and they are great to listen to during my commute, chores, and walks. I also love blogs and newsletters but tend to be stingier with them. This is mostly because they require dedicated time and attention.

As a front-end engineer with an emphasis on React, there are 3 newsletters that I find not only great for my career, but great to read in general:

A geek with a hat by Swizec Teller
Overreacted by Dan Abramov
