+The **`default`** property of the {{domxref("HTMLTrackElement")}} interface represents whether the track will be enabled if the user's preferences do not indicate that another track would be more appropriate. It reflects the {{htmlelement("track")}} element's boolean [`default`](/en-US/docs/Web/HTML/Element/track#default) attribute, returning `true` if present and `false` otherwise.
+
+## Value
+
+A Boolean.
+
+## Example
+
+```js
+const trackElement = document.getElementById("exampleTrack");
+console.log(trackElement.default);
+trackElement.default = true;

+
+The **`kind`** property of the {{domxref("HTMLTrackElement")}} interface represents the type of track, or how the text track is meant to be used. It reflects the {{htmlelement("track")}} element's enumerated [`kind`](/en-US/docs/Web/HTML/Element/track#kind) attribute.
+
+If no `kind` is set, `subtitles` is used. If the attribute is not set to one of the valid enumerated values, it is invalid and `metadata` is used. Other valid values include `captions`, `descriptions`, and `chapters`.
+
+## Value
+
+A string; lowercase `captions`, `descriptions`, `chapters`, `subtitles` or `metadata`.
+
+## Example
+
+Given the following:
+
+```html
+<track src="track.vtt" id="exampleTrack" />
+```
+
+We get the following results:
+
+```js
+const trackElement = document.getElementById("exampleTrack");
+// missing value
+console.log(trackElement.kind); // "subtitles"
+trackElement.kind = "INVALID";
+// invalid value
+console.log(trackElement.kind); // "metadata"
+trackElement.kind = "CAPTIONS";
+// valid value
+console.log(trackElement.kind); // "captions"
