For other Typescript newbies like me that want to understand why this is happening — it’s because the `v4()` function is exported in the ‘uuid’ source code, which means we need to `import` it to gain access to it. So we specifically need to import the `v4` function, and then can use it as we wish:
import { v4 } from ‘uuid’;…v4(); // Produces a UUID
However, if you just see `v4()` in the code, it wouldn’t be immediately obvious that this function returns a UUID. So we can add an alias to enhance code readability:
import { v4 as uuid } from ‘uuid’;…uuid(); // Produces a UUID
See here for the official docs.
