Why is it bad style to `rescue Exception => e` in Ruby?

😎 Why Rescuing Exceptions is Bad Style in Ruby! 💎

So, you're wondering why it's considered bad style to use rescue Exception => e in Ruby? 🤔 Let's dive into the world of Ruby exceptions and explore the reasons behind this unwritten rule! 💡

🚫 The Dreadful rescue Exception 🚫

When it comes to handling exceptions in Ruby, the rescue Exception syntax might seem like a convenient way to catch any unexpected errors that may occur in your code. However, this approach can actually lead to more harm than good! 🤯

🧨 It Can Mask Serious Problems 🧨

Using rescue Exception catches not only the standard exceptions (like StandardError), but also system-level exceptions (like SystemExit and SignalException). By doing so, you're essentially hiding any severe issues that your code might be experiencing. This can make it challenging to spot and debug critical problems! 😱

🔨 Best Practices to the Rescue! 🔧

So, what's the right way to handle exceptions in Ruby?

1️⃣ Be Specific: Instead of rescuing all exceptions, it's recommended to catch specific exceptions that you're expecting. For example, you might want to rescue ArgumentError if you're dealing with user input.

2️⃣ Catch the Most Common: Rescue the most commonly raised exceptions like StandardError, which covers all the generic exceptions that you're likely to encounter in your code.

3️⃣ Always Have a Backup Plan: Implement a top-level exception handler at the highest level of your code. This ensures that any unhandled exceptions will be caught.
