The properties of
href: The entire URL of the current page
host: The hostname and port of the current page
protocol: The protocol used for the current page (such as http or https)
pathname: The path and filename of the current page
You can use these properties to read information about the current URL, or to construct new URLs to navigate to other pages. For example:
// Get the current page URL var currentURL = window.location.href; // Construct a new URL and navigate to it var newURL = "https://example.com/page2.html"; window.location.href = newURL;
window.location object also provides some methods to manipulate the current URL:
assign(url): Navigates to the URL specified by the argument
replace(url): Replaces the current page with the one specified by the argument
reload(): Reloads the current page
Keep in mind that changing the current URL will cause the browser to load a new page, so use these methods with caution.
How to Change the Location of a Web Page Using window.location
// Change the location of the current page window.location = "https://www.example.com/"; // Change the location of the current page, but keep the browser history intact window.location.replace("https://www.example.com/");
The first example simply assigns a new URL to the window.location object, which causes the browser to navigate to the new page. The second example uses the replace() method, which has the same effect but does not create a new entry in the browser’s history. Instead, it replaces the current page in the history, so if the user clicks the back button, they will be taken back to the page that sent them to the current page.
Note that when you change the location of a page using window.location, the new URL must be in the same domain as the current page, unless the page is being opened in a new window or tab. If you need to redirect to a page in a different domain, you can use window.location.href or window.open() instead.
Step 2. Next, you’ll need to type in the following code and replace “https://www.example.com” with the URL you want to redirect to:
window.location = “https://www.example.com”;
Step 3. Press the “Enter” key on your keyboard to execute the code, and you will be automatically redirected to the new URL.
Common Use Cases for window.location in Web Development
- Redirecting to a different page: By changing the URL property of the window.location object, you can redirect the user to a different page. This is commonly used after a user performs a specific action, like submitting a form.
- Reloading the current page: The window.location.reload() method is used to reload the current page. This can be useful if you want to refresh the content of the page after a specific event occurs.
- Getting information about the current URL: The window.location object has several properties that can be used to get information about the current URL, such as href, protocol, host, pathname, etc. This information can be used for various purposes in your web application.
- Manipulating the browser history: The window.location object also provides methods to manipulate the browser’s history, such as window.location.back() and window.location.forward(). These methods allow you to navigate between pages that the user has previously visited.
Overall, the window.location object is an essential tool for any web developer. It provides easy access to the current URL, and allows you to control the user’s navigation within your web application.

Best Practices for Optimizing window.location Performance on Your Website
When it comes to website performance, optimizing the use of the window.location object is essential. Here are some of the best practices to follow:
- Minimize the usage of the window.location object. The more you use it, the slower your website becomes. It’s important to use it only when necessary.
- Avoid using the window.location.reload() method as it causes the page to reload completely, which takes more time.
- Use the window.location.replace() method instead of the window.location.href method whenever you want to redirect the user. This way, the browser doesn’t have to keep the previous page in its session history, which can cause slower website performance.
- Avoid using the window.location.hash property too frequently as it can cause the browser to recalculate the page’s layout each time it changes.
