It’s as easy as calling startsWith() or endsWith() methods on JavaScript string prototype.

As an example we can use string similar to this.

const string = 'Hey, have a great day!'

And check if string is question with simple function.

const isQuestion = str => {
  return str.endsWith('?')
}

When we pass example string to this function it will, of course, return false.

isQuestion(string) // false

You can use startsWith() same way.
