Configuring a mobile toolchain is where a surprising number of beginners quietly give up. Codecademy sidesteps that entirely: you write code in the browser, the platform checks your work immediately, and you keep moving while motivation is still high.

The obvious limitation is that a sandbox is not a real development environment, so you will eventually need to install the tooling properly. Used as a confidence-building first step before the official documentation, though, it does its job well.
