For\nTypeScript users, this package supports both `\"Node10\"` and `\"Node16\"` module\nresolution strategies.\n\n✄------------✄-----------⏶-⏷-----------✄------------✄\n\nThis is an [ESM-only package][x-pkg-esm-wine] built by Babel for use in Node.js\nversions that are not end-of-life. For TypeScript users, this package supports\nboth `\"Node10\"` and `\"Node16\"` module resolution strategies.\n\n✄------------✄-----------⏶-⏷-----------✄------------✄\n\nThis is an [ESM-only package][x-pkg-esm-wine] built by Babel for use in\nbrowser-like environments. For TypeScript users, this package supports both\n`\"Node10\"` and `\"Node16\"` module resolution strategies.\n\n\n\n\n\n\nExpand details\n\n\n\nThat means both CJS2 (via `require(...)`) and ESM (via `import { ... } from ...`\nor `await import(...)`) source will load this package from the same entry points\nwhen using Node. This has several benefits, the foremost being: less code\nshipped/smaller package size, avoiding [dual package\nhazard][x-pkg-dual-package-hazard] entirely, distributables are not\npacked/bundled/uglified, a drastically less complex build process, and CJS\nconsumers aren't shafted.\n\n✄------------✄-----------⏶-⏷-----------✄------------✄\n\nThat means ESM source will load this package via `import { ... } from ...` or\n`await import(...)` and CJS source will load this package via dynamic\n`import()`. This has several benefits, the foremost being: less code\nshipped/smaller package size, avoiding [dual package\nhazard][x-pkg-dual-package-hazard] entirely, distributables are not\npacked/bundled/uglified, and a drastically less complex build process.\n\nThe glaring downside, which may or may not be relevant, is that CJS consumers\ncannot `require()` this package and can only use `import()` in an asynchronous\ncontext. This means, in effect, CJS consumers may not be able to use this\npackage at all.\n\n\n\nEach entry point (i.e. `ENTRY`) in [`package.json`'s\n`exports[ENTRY]`][x-repo-package-json] object includes one or more [export\nconditions][x-pkg-exports-conditions]. These entries may or may not include: an\n[`exports[ENTRY].types`][x-pkg-exports-types-key] condition pointing to a type\ndeclaration file for TypeScript and IDEs, a\n[`exports[ENTRY].module`][x-pkg-exports-module-key] condition pointing to\n(usually ESM) source for Webpack/Rollup, a `exports[ENTRY].node` and/or\n`exports[ENTRY].default` condition pointing to (usually CJS2) source for Node.js\n`require`/`import` and for browsers and other environments, and [other\nconditions][x-pkg-exports-conditions] not enumerated here. Check the\n[package.json][x-repo-package-json] file to see which export conditions are\nsupported.\n\nNote that, regardless of the [`{ \"type\": \"...\" }`][x-pkg-type] specified in\n[`package.json`][x-repo-package-json], any JavaScript files written in ESM\nsyntax (including distributables) will always have the `.mjs` extension. Note\nalso that [`package.json`][x-repo-package-json] may include the\n[`sideEffects`][x-pkg-side-effects-key] key, which is almost always `false` for\noptimal [tree shaking][x-pkg-tree-shaking] where appropriate.\n\n\n\n\n\n\n\n### License\n\n\n\nSee [LICENSE][x-repo-license].\n\n\n\n\n## Contributing and Support\n\n**[New issues][x-repo-choose-new-issue] and [pull requests][x-repo-pr-compare]\nare always welcome and greatly appreciated! 🤩** Just as well, you can [star 🌟\nthis project][x-badge-repo-link] to let me know you found it useful! ✊🏿 Or [buy\nme a beer][x-repo-sponsor], I'd appreciate it.
