<button onclick="count()">find</button>
<div>Results :</div>
<div id="numberOfWords"></div>
<div id="numberOfChars"></div>
<div id="spaceCount"></div>
<script src="./script.js"></script>
</body>
</html>

script.js

function count() {
  var userInput = document.getElementById("user-input").value,
    numberOfWords = countWords(userInput),
    numberOfChars = countCharacter(userInput),
    space = spaceCount(userInput);

  document.getElementById("numberOfWords").innerHTML =
    "Number of words: " + numberOfWords;
  document.getElementById("numberOfChars").innerHTML =
    "Number of Chars: " + numberOfChars;
  document.getElementById("spaceCount").innerHTML =
    "Number of Spaces: " + space;
}
// function to count words
function countWords(string) {
  string = string.replace(/(^\s*)|(\s*$)/gi, "");
  string = string.replace(/[ ]{2,}/gi, " ");
  string = string.replace(/\n /, "\n");
  return string.split(" ").length;
}
// function to count characters
