ERR_REQUIRE_ESM Problem

[v-menzhou]

Saw this issue was posted before, #80. and we are encouraged to create ES module by following the link:

In our case, we have a utility library X that is commonjs module. Since verison 9, mem becomes ES module, therefore, we change X to ES module as well. because X is a lib used by many other commonjs projects. We now are in a difficult position to either to use mem of version 9 below, or to convert all commonjs projects to ES projects.

As for issue 80, my understanding is for those typescript projects, basically, we can not use version 9 or after?

Since mem is a popular utility, and changing it to pure ES module has a huge change impact. Wonder if we could offer distributions of both ES and commonjs module? I do not know how to make this work, the link below is encouraging:

Thanks for your consideration!

I don't have any plans to offer dual package as that is even worse than not: https://gist.github.com/sindresorhus/a39789f98801d908bbc7ff3ecc99d99c#gistcomment-3850849
