 Let's learn about the `Audio` constructor and its common methods.

 The `Audio` constructor, like other constructors, is a special function called with the `new` keyword. It returns an `HTMLAudioElement`, which you can then use to play audio for the user, or append to the DOM for the user to control themselves.

 Let's learn about the different types of audio and video formats.

 You have probably heard of, or even used, a few common ones. If the terms MP3, MP4, MOV, or WebM are familiar to you, those are all different formats for video and audio. And there are quite a few more that are available.

 Let's learn about codecs and how they work.

 If you have worked with videos or audio before, you may have heard about codecs. A codec, short for "encoder/decoder", is an algorithm or software that can convert audio and video between analogue and digital formats.

-
 The `HTMLMediaElement` API is a powerful tool to control the behavior of audio and video elements on your page. It extends the base `HTMLElement` interface, so you have access to the base properties as well as these helpful methods.

 You've already explored some of the methods in a previous lecture about the `Audio` element, such as `play()` and `pause()`. These same methods are available on video elements as well.

-How can you capture video and audio from a local device?
-
 Instead of playing audio and video, you may sometimes want to capture audio or video. The Media Capture and Streams API, or the MediaStream API, allows you to do this.

 In order to use the API, however, you need to create the `MediaStream` object. You could do this with the constructor, but it would not be tied to the user's hardware. Instead, the `mediaDevices` property of the global `navigator` object has a `getUserMedia()` method for you to use.

-What are some other examples of video and audio APIs?
-
 You've learned about the `HTMLMediaElement` and MediaStreams APIs, but there are a few more APIs that can be quite helpful in working with video and audio.

 The first is the Screen Capture API. As the name might suggest, this API allows you to record a user's screen. This API is exposed by calling the `getDisplayMedia()` method of the `mediaDevices` object and consuming the returned media stream.

 Dates and times in JavaScript have not always been easy to work with. In a professional codebase, you will probably be using a library that has solved a lot of those issues for you.

 But there will be times where you will need to work JavaScript's built-in `Date` object.
