What is Browser Console? How to open it?

What is Browser Console?

Your browser’s developer tool includes a browser console. This console outputs messages about the web page you are looking at, such as errors, warnings, network requests, and JavaScript custom logs.

It’s like a window into the site’s inner workings. Whether you’re debugging a JavaScript bug or monitoring network calls, the console is where you want to be for browser-side diagnostics.
