Where can I see all objects I can make with the "new" operator in Chrome?

Title basically. I want to know all the objects I can make with new in chrome - which are specific to Chrome/Chromium. For example:

new MessageChannel();

new TextEncoderStream();

new EyeDropper();

Is there a list of these methods somewhere?

Solution

  • Since these are properties of window, you can try something like this:

    names = []

for (let k of Object.getOwnPropertyNames(window)) {
  let v;
  try {
    v = window[k]
  } catch (e) {
  }
  if (k.match(/^[A-Z]/) && typeof v === 'function')
    names.push(k)
}

console.log(names.sort())

    It doesn't tell whether these functions are really constructors though.
