Further detail

If you change the first line of index.js to

import merge from "deepmerge"

then Webpack correctly returns the function.

If you do a CommonJS import:

const merge = require("deepmerge")

then Webpack returns the exports property on whatever was exported by deepmerge, which is undefined.
