How to Detect the Browser and Version Using JavaScript

Identifying the user's browser and its version is crucial for web developers to tailor user experiences and provide optimal website functionality. JavaScript offers a convenient solution to this challenge.

The Navigator object provides access to various browser-specific properties. The userAgent property contains a string representing the user's browser and its version. However, parsing this string to extract specific information can be tricky.

The provided JavaScript code simplifiesthe process by utilizing regular expressions to parse the userAgent string. It first identifies the browser name and then uses additional regular expressions to determine the version number, handling edge cases for browsers such as Microsoft Edge (Chromium-based).

The example included in the answer demonstrates the usage of the code. When executed in a browser, it logs the browser name and version to the console. For instance, in Google Chrome version 89, it would output:

Chrome 89

By leveraging JavaScript's capabilities, developers can easily obtain accurate browser and version information, empowering them to create more customized and reliable web experiences.
