<script>
// defining a list of chocolates
var chocolates = ["Mars", "Hersheys", "Kitkat", "Twix"];

// defining our functions
function checkMars(choc) {
  return choc == "Mars";
}

// this function uses array some method and takes in
// our function checkMars as an argument. This will return
// a value true of false. 
function myfunc() {
  document.getElementById("demo").innerHTML = chocolates.some(checkMars);
}
