Introduction

Card payments with Stripe should be performed with PaymentIntents.

This API was created to handle modern payments, where the cardholder's bank may require the user to authenticate themselves with the bank before a payment can be authorized.

Authentication requirements first started to appear with European banks regulated by PSD2 which introduced [Strong Customer Authentication

When Babel 6 came out, it was hard for a lot of packages to upgrade because it was essentially an entirely different category of thing than Babel 5. So what happened was that some packages upgraded, and some didn't — at least not straight away.

Some projects took the prima facie enlightened view that packages should expose untranspiled code, so that the consumers of that code could determine for themselves what needed to get transpiled based on the environments they supported.

That was a costly decision. If I was the author of an app that was using Babel 6, I couldn't import a library that was still using Babel 5 and shipping untranspiled code (because the configs were completely incompatible), and vice versa. Frankly, it was a bloody nuisance. We are bad at anticipating these sorts of issues. It will happen again at some point.

Adding a few extra bytes to pkg.main or pkg.module is a small price to pay for things just working. As well as avoiding the aforementioned headaches, it means that your

A lot of people mentioned other immutable JS libraries after reading my post. I thought it would be good to make a list of available ones.

There are two types of immutable libraries: simple helpers for copying JavaScript objects, and actual persistent data structure implementations. My post generally analyzed the tradeoffs between both kinds of libraries and everything applies to the below libraries in either category.

Libraries are sorted by github popularity.

Minimal example: transcode from MP3 to WMA:
ffmpeg -i input.mp3 output.wma

You can get the list of supported formats with:
ffmpeg -formats
