The API in Code
How the bitbybit API looks in TypeScript - the bitbybit constant that holds every function, the Bit namespace of option objects and types, the BabylonJS context - with a worked example to run on the page.
Files and imports
How a TypeScript script spans several files and folders - main.ts as the file the run starts from, making, renaming, moving and deleting files, importing your own files and JSON data, and the limits a script keeps to.
IntelliSense and errors
How the TypeScript editor helps as you type - suggestions at every dot, a function's documentation on hover, mistakes underlined before the run with a count on the file - and where the errors of a run appear.
The Script Runtime
What a TypeScript or Blockly script can reach when it runs in the editor - bitbybit, Bit, BABYLON and its GUI - what it cannot, top-level await, the console, how runs start and end, and why imports are limited to the script's own files.
