A beginner's intro to coding zero-knowledge proofs
Noir, built by Aztec, is the newest language of the pack and is under active development. It is distributed as nargo, a rust-based CLI, and as a set of npm packages. The npm packages releases seem to lag slightly behind the crate, which has the bleeding edge features and only got its first stable release a few days ago (early February). Both the rust crate and the npm package can be used to compile Noir programs, generate and verify proofs, and create a verifier Solidity contract.

A beginner's intro to coding zero-knowledge proofs
To me, Halo2 had the steepest learning curve by far. Not just because of having to understand how PLONKish arithmetization works to build the circuits, but mostly because I found Halo2's API quite complex and its documentation hard to find. There are also few resources for learning Halo2: the best I found were the 0xparc course which provides a few really valuable code samples, as well as the examples in the main repo. You may also want to check out awesome-halo2 for updated resources.
