Does the current environment have import() support?
At the time of this writing, node v12.17+, v13.2+ and v14.0+ has support for dynamic import(); the syntax is supported in node v10+.
The former can be checked in the package‘s main export, which is an async function that returns a boolean indicating if the current environment fully supports dynamic import. Note that in node v12.17 - v12.19 and v13.4 - v13.13, an ExperimentalWarning will be logged.
The latter can be checked with 'has-dynamic-import/syntax', which is a function that returns a boolean indicating if the current environment supports parsing the syntax of dynamic import.
Simply clone the repo, npm install, and run npm test
