Exception handling is an important approach which is designed to handle unexpected occurrence of code error in [programming language](https://www.mindstick.com/articles/329035/5-most-in-demand-programming-languages-to-consider-for-your-app-development-in-2022). In other words, Exception handling is the occurrence of unexpected code error due to which the [execution](https://www.mindstick.com/blog/178/synchronous-and-asynchronous-command-execution-in-c-sharp-dot-net) of program may be terminated.\ There is a specific way to [handle the exception](https://www.mindstick.com/forum/159349/who-and-how-handle-the-exception-when-we-use-throws) in [JavaScript](https://www.mindstick.com/articles/874/how-to-create-watermark-text-for-textbox-by-using-javascript). Try, catch and finally are used to handle the exception. Try contains those blocks of code there is probability to occurrence unexpected code error and when exception is raised then [catch block](https://www.mindstick.com/forum/159348/how-does-an-exception-find-the-correct-catch-block) catches that exception and handle that exception i.e. catch block contains exception handler code. Here I am giving a small example to how exception handles within the JavaScript code. Here I am taking two input number1 and number2 and print division result of these two numbers. **Example:** How to [handle exception](https://www.mindstick.com/forum/162065/how-to-handle-exception-globally-in-dot-net-core) through the JavaScript ``` Exception Handling
