How to Force Browsers to Load the Latest JavaScript Code?

Clearing the Cache in JavaScript

Problem:

Despite deploying updated JavaScript code, the browser still retrieves the cached version, preventing users from accessing the latest functionality.

Answer:

While it's not possible to completely clear a browser's cache using pure JavaScript, one workaround is to utilize the window.location.reload(true) method. This method instructs the browser to ignore cached items and retrieve new copies of the page, including JavaScript files. However, it only clears the cache for the current page.

Alternative Solutions:

A more effective strategy is to version the JavaScript file path or filename to force browsers to load the latest version. This involves adding a unique identifier to the file name, such as a version number or timestamp. For example:

script.js?v=1.2.3
