I really enjoy THREE.js, but I don't think it gives you the same level of understanding of WebGL that this link does. This is like taking a course on how OpenGL works in the browser. That being said, the amount of code needed to make a hello world in WebGL2, not including learning GLSL, is a bit daunting, and if you showed this tutorial to me first, I might not have gotten interested in doing any 3D coding in the browser. The Three.js WebGL abstraction library makes the task much less daunting and gives you some force multipliers that WebGL does not, it makes a lot of assumptions for you, and still gives you a fair amount of control over the action.
