It took a few years, but I finally understand why member functions of classes in JavaScript aren't automatically bound to their objects, in particular when used in callback arguments.

In most object-oriented languages, functions are members of a class--they exist in memory only once, and when they are called, this is simply a hidden argument of the function which is assigned to the object that's calling it. Python makes this explicit by requiring that the first argument of a class's member function be self (Python's equivalent of this--you can name self whatever you want, but self is the convention).

class MyClass:

<button onclick="recordStop()" id="record-stop-button">Record</button>
<button onclick="playAudio()" disabled id="play-audio-button">Play</button>
<script>
const recordAudio = () =>
  new Promise(async resolve => {
    const stream = await navigator.mediaDevices.getUserMedia({ audio: true });
    const mediaRecorder = new MediaRecorder(stream);
    const audioChunks = [];

    mediaRecorder.addEventListener("dataavailable", event => {

Using the classnames.bind method

Many people who work with React are familiar with the excellent classnames library. If you aren't familiar, it provides a simple function for gluing classnames together. In web programming in general, there are many times that we need to add or remove multiple classes based on conditional logic. The classnames library makes this easy.

More and more developers are embracing CSS Next and the power of CSS modules. However, when you add CSS modules to your react components, working with classnames gets more difficult. Typically, CSS modules is implemented with class name mangling. Transforming human readable class name strings into unique identifiers helps ensure that every class name in your app is unique.

This means that you can write your component CSS in isolation without worrying about the dreaded class name collisions that have plagued CSS
