Why Reload a Page with JS?
location.reload() method, which is a part of the
window.location object. Here's a simple example:
When this line of code is executed, the current document will be reloaded. It's as simple as that!
location.reload() method does accept an optional parameter. If you set it to
true, it will force a reload from the server. If you set it to
false or leave it empty, it will reload from the browser cache, if available.
Force Reload vs Normal Reload
A normal reload occurs when you call
location.reload() without any arguments or with a
false argument. In this case, the browser will try to reload the page from its cache. This can be faster, but it might not fetch the most recent version of the page from the server.
window.location.reload(); // normal reload
window.location.reload(false); // also a normal reload
A force reload, on the other hand, occurs when you call
location.reload() with a
true argument. This forces the browser to bypass its cache and request the page from the server. This ensures that you get the most recent version of the page, but it might be slower due to the server request.
window.location.reload(true); // force reload
So, whether you want to use a normal reload or a force reload depends on your specific needs and the behavior you want to achieve.

This can be useful in scenarios like a news website where you want to refresh the content every few minutes or an online auction where you want to update the current bid status.

Here's an example:
In this example, the page will reload every 5 seconds (5000 milliseconds).

Sometimes, you may want to reload a page based on a specific user event, like a button click, form submission, or a certain interaction.
Consider a scenario where you have a button, and you want to reload the page when this button is clicked. You can achieve this by using the
Here's a simple example:
<button onclick="location.reload();">Reload Page</button>
In this example, the page will reload every time the button is clicked.
