Pictorial Presentation:

JavaScript: Break an address of an url and put it's part into an array.

Sample Solution:

HTML Code:

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width">
  <title>Break an address of an url and put it's part into an array.</title>
</head>
<body>

</body>
</html>

JavaScript Code:

function break_address(url_add) {
    var data = url_add.split("://")
    var protocol = data[0];
    data = data[1].split(".com");
    var domain = data[0];
    data = data[1].split("/");

    if(data[1]){
        return [protocol,domain,data[1]]
    }

    return [protocol,domain]
}

var url_add = "https://www.w3resource.com/javascript-exercises/"
console.log("Original address: "+url_add)
console.log(break_address(url_add))

Sample Output:

Original address: https://www.w3resource.com/javascript-exercises/
["https","www.w3resource","javascript-exercises"]

Flowchart:

ES6 Version:

function break_address(url_add) {
    let data = url_add.split("://");
    const protocol = data[0];
    data = data[1].split(".com");
    const domain = data[0];
    data = data[1].split("/");

    if(data[1]){
        return [protocol,domain,data[1]]
    }

    return [protocol,domain]
}

var url_add = "https://www.w3resource.com/javascript-exercises/"

JavaScript: Tips of the Day

How to insert an item into an array at a specific index (JavaScript)?

What you want is the splice function on the native array object.

arr.splice(index, 0, item); will insert item into arr at the specified index (deleting 0 items first, that is, it's just an insert). In this example we will create an array and add an element to it into index 2:

var arr = []; arr[0] = "Jani"; arr[1] = "Hege"; arr[2] = "Stale"; arr[3] = "Kai Jim"; arr[4] = "Borge"; console.log(arr.join()); arr.splice(2, 0, "Lene"); console.log(arr.join());
