The Array.join() method of JavaScript is used to join the array and return as a string.
The syntax is as follows −
array.join(separator)
Above, set the separator to be used as a parameter.
Let us now implement the Array.join() method in JavaScript minus;
Example
<!DOCTYPE html>
<html>
<body>
<h2>Demo Heading</h2>
<p>Is this is an array?</p>
<p id="test"></p>
<script>
var arr = ["Accessories", "Electronics", "Books", "Pet Supplies"];
var res = document.getElementById("test");
res.innerHTML = Array.isArray(arr)+" = "+arr.join()
</script>
</body>
</html>Output
Example
<!DOCTYPE html>
<html>
<body>
<h2>Demo Heading</h2>
<p id="test"></p>
<script>
var arrStud = ["Laptop", "Desktop", "Tablet"];
document.getElementById("test").innerHTML = "Initial array = "+arrStud+", <br>String with seperator = "+arrStud.join("...");
</script>
</body>
</html>Output
