This module exports two functions:
addEventListener(target, type, handler, options)
removeEventListener(target, type, handler, options)
These work like
target.addEventListener(type, handler, options), except that
optionsis allowed to be an object even in browsers which don't yet support that. In that case, only the options object's
captureproperty is respected.
See https://github.com/WICG/EventListenerOptions/blob/gh-pages/explainer.md for more information on the options parameter.
This module also includes an optional polyfill. Use the following to override the addEventListener and removeEventListener methods on all EventTargets with replacements that support an options object if necessary:
