Test

  • Determines if an API is statically invoked (ex. document.querySelector())
  • Determines if an API is a CSS or JS API
  • Provides compatibility information from @mdn/browser-compat-data

import AstMetadata from "ast-metadata-inferer";

const [firstRecord] = AstMetadata;
console.log(firstRecord);
// {
//   "language":"js-api",
//   "protoChain":["document","querySelector"],
//   "protoChainId":"document.querySelector",
//   "astNodeTypes":["MemberExpression"],
//   "isStatic":true,
//   "compat": {
//     support: {
