Install the module
npm install @wordpress/annotations --saveThis package assumes that your code will run in an ES2015+ environment. If you're using an environment that has limited or no support for ES2015+ such as IE browsers then using core-js will add polyfills for these methods.
You need to include wp-annotations as a dependency of the JavaScript file in which you wish to use the Annotations API.
