[`core-js-compat` package](https://github.com/zloirock/core-js/packages/core-js-compat) contains data about the necessity of [`core-js`](https://github.com/zloirock/core-js) modules and API for getting a list of required core-js modules by browserslist query.
```js
const {
list, // array of required modules
targets, // object with targets for each module
} = require('core-js-compat')({
targets: '> 2.5%', // browserslist query
filter: 'es.', // optional filter - string-prefix, regexp or list of modules
});
console.log(targets);
