The lesson player is where you actually take a lesson. Unlike a video player, it presents interactive content alongside the Dynamic Workspace, so reading and doing happen together.
  • Step through the lesson content at your own pace.
  • Practice inline — exercises open the workspace right where you need them.
  • Move between lessons in a course using the navigation controls.

​
The interactive panel

Because content is interactive rather than a fixed recording, the player can adapt what it shows — code, terminal, preview, or explanation — to the moment in the lesson. This is the same context-aware behavior described in the workspace overview.

​
Your place is saved

Progress is tracked automatically (see Progress & Library), so you can leave and resume any time.
