Object-Oriented JavaScript — Built-in Browser Objects

Object-Oriented JavaScript — Built-in Browser Objects

Things we can do with the window object.

JavaScript is partly an object-oriented language.

To learn JavaScript, we got to learn the object-oriented parts of JavaScript.

In this article, we’ll look at built-in browser objects.

The window.location Property

The window.location property lets us get the URL of the page and redirect it to another one.

For instance, we can use location.hostname to get the hostname.

And href gets us the full path.

pathname gets us the segment before the query string.

port gives us the port.

search gives us a query string.

We can get all the properties of the location object with the loop:

for (const key in location) {
  if (typeof location[key] === "string") {
    console.log(key, location[key]);

We loop through each property with the location object.

We set the location.href property to redirect to a new URL.

For example, we can write:

window.location.href = 'http://www.example.com';

Also, we can write:

location.href = 'http://www.example.com';
location = 'http://www.example.com';

replace is almost the same as assign , but it doesn’t create a new browser history entry.

We can use it by writing:


To reload a page, we can write:


We can also assign window.location.hre to itself to reload the page:

window.location.href = window.location.href;
location = location;

JavaScript: Chessboard Program

Exercise from Eloquent JavaScript. Today, we will write a function that forms a chessboard. You can find the exercise in the Eloquent Javascript book (3rd edition, chapter 2; Program Structure). Write a program that creates a string that represents an 8×8 grid, using newline characters to separate lines. At each position of the grid there is either a space or a “#” character. The characters should form a chessboard.

Learning JavaScript: Development Environments for JavaScript Programming

One of the nice things about learning JavaScript these days is that there is a plethora of choices for writing and running JavaScript code. In this article, I’m going to describe a few of these environments and show you the environment I’ll be using in this series of articles.

Learning JavaScript: Data Types and Variables

To paraphrase the title of an old computer science textbook, “Algorithms + Data = Programs.” The first step in learning a programming language such as JavaScript is to learn what types of data the language can work with. The second step is to learn how to store that data in variables. In this article I’ll discuss the different types of data you can work with in a JavaScript program and how to create and use variables to store and manipulate that data.
