Use the event name in methods like addEventListener(), or set an event handler property.

addEventListener("play", (event) => {});

onplay = (event) => {};

A generic Event.

These examples add an event listener for the HTMLMediaElement's play event, then post a message when that event handler has reacted to the event firing.

Using addEventListener():

const video = document.querySelector("video");

video.addEventListener("play", (event) => {
  console.log(
    "The Boolean paused property is now 'false'. Either the play() method was called or the autoplay attribute was toggled.",
  );
});

Using the onplay event handler property:

const video = document.querySelector("video");

video.onplay = (event) => {
  console.log(
    "The Boolean paused property is now 'false'. Either the play() method was called or the autoplay attribute was toggled.",
  );
};
