 Created a watch mode for the build.ts script without much fuss at all.  `deno run --watch` only watches the script and modules that you call directly, so I had to use the runtime API to use `Deno.watchFs`; it had a problem where it ran modify events three times in a row, so I also imported a recommended debounce script from the std library (versionless because we're all insane: https://jsr.io/@std/async/doc/debounce).
 
+## Deno test
+
+Needed a deno.json file, with "DOM" in "lib".
+
+Needed to run with `unstable-sloppy-imports` to ignore lack of ".ts" extensions.
+
+Needed to add to my tsconfig.json:
+
+```json
+    "allowImportingTsExtensions": true,
+    "noEmit": true,
+    "module": "ES2020",
+```
+
+This is because I was running `require('index')` in the index test.
+
+I needed to import tests to a single test file in order for Deno to pick up on Jest types:
+
+`// @deno-types=npm:@types/jest`
+
+## Deno Check
+
+Needed a global.d.ts file to properly type check files, but I also needed to ignore the file for linting:
+
+```ts
+// deno-lint-ignore-file
+declare var gtag: (...args: unknown[]) => void;
+
+declare var dataLayer: unknown[];
+
+declare var process: NodeJS.Process
+```
+
+If I didn't ignore the file for linting I would get:
+
+> error[no-var]: `var` keyword is not allowed.
