Pass an optional options object for custom settings.

superplaceholder({

	sentences: [ 'Something to show', 'Another thing to show'],
	options: {
		// delay between letters (in milliseconds)
		letterDelay: 100, // milliseconds
		// delay between sentences (in milliseconds)
		sentenceDelay: 1000,
		// should start on input focus. Set false to autostart
		startOnFocus: true, // [DEPRECATED]
		// loop through passed sentences
		loop: false,
		// Initially shuffle the passed sentences
		shuffle: false,
		// Show cursor or not. Shows by default
		showCursor: true,
		// String to show as cursor
		cursor: '|',
		// Control onFocus behaviour. Default is `superplaceholder.Actions.START`
		onFocusAction: superplaceholder.Actions.[NOTHING|START|STOP]
		// Control onBlur behaviour. Default is `superplaceholder.Actions.STOP`
 		onBlurAction: superplaceholder.Actions.[NOTHING|START|STOP]

Manually Controlling a superplaceholder instance:

// Complete manual control
const instance = superplaceholder({

 options: {
  onFocusAction: superplaceholder.Actions.NOTHING
