After heavy consideration and research I’ve decided not to spend a bunch of money on a bootcamp. So where to start?

I’m very interested in web3 specifically dapps and defi but I’ve only done conceptual, surface level reading. I definitely wanna try my hand at coding and the technical stuff before jumping into a bootcamp that may or may not be super helpful. Anyone know any good resources to start learning how to code and build projects? (for free or low cost)
