Hi there!

While perusing StackOverflow's 2023 Developer Survey (yes, we developers have our own version of celebrity gossip), I couldn’t help but notice that our trusty VSCode is still riding high as the undisputed IDE champ. With a whopping 73% of the developer vote, it’s safe to say that VSCode has firmly planted its flag. But, like any superstar, it’s not immune to the spotlight’s glare, especially when it comes to security.
