About This Episode:
Even the best-written code can run into unexpected situations — and that’s where error handling comes in. In this episode, you’ll learn how to make your programs more reliable by anticipating problems and handling them gracefully.
� What you’ll learn:
- Why handle errors? The importance of defensive programming.
- try, catch, finally — how to catch problems without crashing your program.
- Throwing custom errors when you detect something invalid.
- Practical example with input validation (like stopping someone from dividing by zero).
� Why it matters:
Professional developers don’t just write code that works — they write code that fails gracefully. Error handling is what separates quick scripts from robust applications.
By the end of this episode, you’ll know how to protect your code against the unexpected — and keep your users from seeing cryptic crashes. �
