The XRInputSourceArray interface's entries() method returns a JavaScript iterator which can then be used to iterate over the key/value pairs in the input source array. Each item in the array is an XRInputSource object.

Most frequently, you will use this in tandem with statements such as for...of.

None.

An iterator which can be used to walk through the list of XRInputSource objects included in the input source array.

This example snippet gets the list of inputs for a session and tries to handle each type of input device it supports using.

let sources = xrSession.inputSources;

for (const input of sources.entries()) {
  if (input.gamepad) {
    checkGamepad(input.gamepad);
  } else if (
    input.targetRayMode === "tracked-pointer" &&
    input.handedness === player.handedness
  ) {
    /* Handle main hand controller */
    handleMainHandInput(input);
  } else {
    /* Handle other inputs */
  }
}

For each input in the list, gamepad inputs are dispatched to a checkGamepad() with the input's Gamepad object, taken from its gamepad property, as an input

For other devices, we look for tracked-pointer devices in the player's main hand, dispatching those to a handleMainHandInput() method.
