 The API is the same as [acorn](https://github.com/acornjs/acorn), but the following syntax features are enabled by default:
 
- - Bigint syntax `10n`
  - Numeric separators syntax `10_000`
  - Public and private class instance fields
  - Public and private class static fields
- - Dynamic `import()`
- - The `import.meta` property
- - `export * as ns from` syntax
 
 And the following options have different defaults from acorn, to match Node modules:
 
- - `ecmaVersion: 2019`
+ - `ecmaVersion: 2020`
  - `allowHashBang: true`
  - `allowReturnOutsideFunction: true`
