The workers from Moment.js work on various tasks simultaneously

Exploring the latest versions of Webpack and Moment.js.
Noticed an interesting behavior in my production build - multiple (~30) files are being generated by moment.js with names like *random-hash*.worker.js.

Is this normal?

Check out a screenshot here

Haven't configured any additional options and wondering if this is expected. Currently using other WebWorkers in the project and would prefer to have only mine. Could it be related to the use of the worker-loader webpack plugin?

Adding a hash to a file makes it easier to distribute your code publicly in the future.

Consider this scenario: you've created an app and you want it to be user-friendly, with fast download times for those on slow connections. At the same time, you need the ability to update the app on the server so that all users always have access to the latest version. File caching in users' browsers seems like a good solution, but it comes with its own set of challenges...

By adding a hash to the filename, web browsers can cache the file indefinitely. Then, when you update your code, a new file with a new hash is generated.

Using this method, when index.js is downloaded, the references will be different, prompting the web browser to download any missing files and use those from its cache otherwise.
