How browser JavaScript is written in this repo — both surfaces now speak one modern dialect and this says what that means for the code you type, where ES modules are impossible and where they are merely unused, and how to pick a feature (Baseline plus a file:// gate). Covers functional idiom over imperative DOM work, the shared helper layer, modular structure without a bundler, DRY across the report and the panel, keeping features isolated so one failure cannot blank a page, readability…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Writing JavaScript here
There is no bundler, no npm, no TypeScript and no build step. The ordered parts under
`ui/report/` and `ui/panel/` are concatenated by Python into exactly one inline `<script>` per
page. The mechanics of that — ordering, the byte pins, splitting — belong to
`refactoring-the-assembled-ui`. This file is about the code you type.
## Which dialect
**Modern ES, in both — and both surfaces now speak it.** This section used to carry a table
showing `report.js` as strictly ES5 against a modern `panel.js`; that gap was closed, and the
table went on describing it. Re-derive rather than reading a number here:
```bash
for d in report panel; do
printf '%s: var=%s function()=%s\n' "$d" \
"$(grep -rho '\bvar ' plugins/audit/scripts/ui/$d/ | wc -l | tr -d ' ')" \
"$(grep -rho 'function *(' plugins/audit/scripts/ui/$d/ | wc -l | tr -d ' ')"
done
```
Both are at zero `var` and zero `function ()`. What is NOT yet symmetric is JSDoc — the report's
parts carry a block per exported behaviour and the panel's parts carry almost none — and since
this project has no TypeScript, JSDoc is the type system it gets. Types must be specific

How to install
mdr add aleksandarbisevac/claude-plugins/writing-javascript@sha256:49e7c709adebe26aThe line at the top of this page pins the label git:20261019.1b5a047, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
