NPM Commands, Scripts, Life-cycle Phases

The following describes the behaviour of several npm commands, particularly w.r.t. the scripts that are run in each, for NPM version 6.5.0.

The package that linked you here is now pure ESM. It cannot be require()'d from CommonJS.

This means you have the following choices:

Use ESM yourself. (preferred)
Use import foo from 'foo' instead of const foo = require('foo') to import the package. You also need to put "type": "module" in your package.json and more. Follow the below guide.
If the package is used in an async context, you could use await import(…) from CommonJS instead of require(…).
Stay on the existing version of the package until you can move to ESM.

	// A short snippet for detecting versions of IE in JavaScript
	// without resorting to user-agent sniffing
	// ----------------------------------------------------------
	// If you're not in IE (or IE version is less than 5) then:
	// ie === undefined
	// If you're in IE (>=5) then you can determine which version:
	// ie === 7; // IE7
	// Thus, to detect IE:
	// if (ie) {}
