Hey guys,
I'm a little confused.
At the end of the video, we write the functions for calculating the total price of the quantity of items selected and the errors in case the amount deposited is less than the total price.
With this we use throw statements, as obviously we're throwing errors such as insufficientFunds.
But why don't we then write all the Do and Catch stuff for the errors? Why are we moving on?
Any explanation would be very much appreciated. thank you.

When something went wrong in runtime , another parts of the program can catch these errors and notify the user or can change program flow etc..And then program is not halted exceptionally. While you writing a program, everything may be true or correct but in runtime, somethings can produce unexpected results. In this time you can handle these logical errors or another strange situations with these way...
In C# , we are using try - catch code block for critical operations in methods or class.
