Lesson 8 - Exception Handling

8.1 What Are Exceptions

Exceptions are errors or unexpected events that interrupt the normal execution of a program.

For example, if we try to divide a number by zero, this will show an error.

But you don't have to worry about it!

JavaScript introduces an amazing solution for handling exceptions and maintaining normal execution of your program even if an error occurs.

For example:

console.log(a / 10);

The above line of code will generate an error because the variable a isn't defined.

Benefits of Handling Exceptions Handling exceptions provides you with the following benefits:

• Exception handling ensures that your application can manage unexpected conditions without crashing.
• Exception handling helps maintain a smooth user experience.
• Exception handling allows for proper resource management.
• Exception handling lets you control the flow of your program more precisely.
