Package description

What is @babel/compat-data?

The @babel/compat-data package provides data about the environment features that Babel can target. It includes information about browser and JavaScript engine versions that support various ECMAScript features. This data is used by Babel to determine which transformations and polyfills are necessary for a given target environment.

What are @babel/compat-data's main functionalities?

Environment Data Retrieval

Retrieve compatibility data for the last two versions of browsers. This is used in Babel's preset-env to determine which transformations/polyfills are needed.

"last 2 versions"

Specific Feature Data

Get data about a specific ECMAScript feature, such as arrow functions, to see which environments support it natively.

"es6.arrow-functions"
