| 10 | ECMAScript spec abstract operations.
|
|---|
| 11 |
|
|---|
| 12 | Every operation is available by edition/year and by name - for example, `es-abstract/2020/Call` gives you the `Call` operation from ES2020, `es-abstract/5/Type` gives you the `Type` operation from ES5.
|
|---|
| 13 |
|
|---|
| 14 | All abstract operations are also available under an `es5`/`es2015`/`es2016`/`es2017`/`es2018`/`es2019`/`es2020`/`es2021` entry point, and as a property on the `main` export, but using deep imports is highly encouraged for bundle size and performance reasons. Non-deep entry points will be removed in the next semver-major release.
