Polyfills
We provide the most common APIs in a target specific bundle. APIs that are detectable globals are replaced per usage with an import to the poylfill.
> If a feature is not listed here check if it is already supported by IE 11.

Two sub scripts will came in handy from time to time:

- npm start test.watch: re-run tests on change -npm start test.coverage: creates a coverage report at coverage/lcov-report/index.html

`$3`

1. Update changelog 2.npm run format3.npm test4. git commit -a -m "chore: prepare release
5. [npm version [\ | major | minor | patch] -m "chore: release"](https://docs.npmjs.com/cli/version)

Folder Structure

$3

Put all your source code including your test files here. Test files
are matched using the following regexp:

- src/*/__tests__/.{js,jsx,ts,tsx}: matches every file within a __tests__ directory but not in child directories
- src/*/.{spec,test}.{js,jsx,ts,tsx}: matches .test.js and .spec.js files; some for the other extensions

$3

This directory is used by snowpack on npm start to render a preview of your code.
Modify src/__preview__/app.svelte to match your needs.
