Write modern JavaScript and TypeScript — ES6+ features, async/await, modules, destructuring, optional chaining, TypeScript types, and modern tooling. Use when writing JavaScript/TypeScript for BigCommerce themes, apps, or headless storefronts.
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
# Modern JavaScript & TypeScript
## Before writing code
**Fetch live docs**: Web-search `site:developer.mozilla.org javascript` for MDN JavaScript reference. Check `https://www.typescriptlang.org/docs/` for TypeScript documentation.
## ES6+ Features
### Arrow Functions
Concise function syntax with lexical `this`:
- `const add = (a, b) => a + b;`
- Implicit return for single expressions
- No own `this`, `arguments`, `super`, or `new.target`
### Template Literals
String interpolation and multi-line strings:
- `` `Hello, ${name}!` ``
- Tagged templates for DSLs
### Destructuring
Extract values from objects/arrays:
- `const { name, price } = product;`
- `const [first, ...rest] = items;`
- Default values: `const { name = 'Unknown' } = product;`
- Nested: `const { address: { city } } = customer;`
### Spread / Rest
- Spread: `[...arr1, ...arr2]`, `{ ...obj1, ...obj2 }`
- Rest: `function(...args) {}`, `const { a, ...rest } = obj;`
### Modules (ES Modules)
- `import { func } from './module.js';`
- `export const value = 42;` / `export default class {}`
- Dynamic: `const mod = await import('./lazy.js');`
### Optional Chaining & Nullish Coalescing

How to install
mdr add orcaqubits/agentic-commerce-skills-plugins/js-modern@sha256:dc909d5630a9aee6The line at the top of this page pins the label git:20260309.786511c, 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.
