How To

Class: EventHandle

Examples

const evt = obj.on('test', (a, b) => {
  console.log(a + b)
})
obj.fire('test')

evt.off() // easy way to remove this event
obj.fire('test') // this will not trigger an event

// store an array of event handles
let events = []

events.push(objA.on('testA', () => {}))
events.push(objB.on('testB', () => {}))

// when needed, remove all events
events.forEach((evt) => {
  evt.off()
})
events = []
