<h2>JavaScript Array Methods</h2> 
​
<h2>join()</h2>
​
<p>The join() method joins array elements into a string.</p>
​
<p>It this example we have used " * " as a separator between the elements:</p>
​
<p id="demo"></p>
​
<script>
var fruits = ["Banana", "Orange", "Apple", "Mango"];
document.getElementById("demo").innerHTML = fruits.join(" * ");
</script>
​
</body>
</html>
​

<!DOCTYPE html>

​
<h2>JavaScript Expressions</h2>
​
<p>Expressions compute to values.</p>
​
<p id="demo"></p>
​
<script>
document.getElementById("demo").innerHTML = 5 * 10;
</script>
​
</body>

<h2>JavaScript Numbers</h2>
​
<p>If you add two numeric strings, the result will be a concatenated string:</p>
​
<p id="demo"></p>
​
<script>
var x = "10";
var y = "20";
var z = x + y;
document.getElementById("demo").innerHTML = z;
</script>
