Allowing my tweet button to share the random quotes

Good morning everyone, I know this question has been asked before, but as a Noob to Javascript which i am struggling to learn, I cannot fathom out how to get my Twitter button to share the random quotes. If possible could a kind dev please explain to me how to actually type it out. I have a good understanding of HTML, CSS and Bootstrap but would appreciate someone explaining this to me.

Many Thanks in advance.

var quotes = [
  "\'It is never too late to be what you might have been.\' - George Eliot",
  "\'What lies behind us and what lies before us are tiny matters compared to what lies within us.\' - Henry Stanley Haskins",
  "\'Great thoughts speak only to the thoughtful mind, but great actions speak to all mankind.\' - Emily P. Bissell",
  "\'I haven’t failed. I’ve just found 10,000 ways that don’t work.\' - Thomas Edison",
  "\'In between goals is a thing called life, that has to be lived and enjoyed.\' - Sid Caesar"
]
function newQuote() {
  var randomNumber = Math.floor(Math.random() * (quotes.length));
  document.getElementById('quoteDisplay').innerHTML = quotes[randomNumber];
}

Solution

Your link's target is static, it's always twitter.com/intent/tweet/?text. I'm not familiar with the Twitter API, but I guess it expects something like ?text=some&encoded&text at the end of the URL. You need to set the value for the text :

<a href="" id="twitterLink">

function newQuote() {
  var randomNumber = Math.floor(Math.random() * (quotes.length));
  document.getElementById('quoteDisplay').innerHTML = quotes[randomNumber];

  document.getElementById('twitterLink').href = "http://twitter.com/intent/tweet/?text=" + encodeURIComponent(quotes[randomNumber])

}
