DND errors can be difficult to debug, as they can be caused by a variety of issues. It is important to check the code for any typos or incorrect references, as well as ensuring that all documents and objects that are being referenced actually exist. Additionally, it is important to check that the code is being run in the correct environment, as this can also cause DND errors.
As mentioned above, functions are used to perform specific tasks related to your code. They can take in any kind of data as parameters (arguments) and will execute whatever code you specify inside the function. Objects are stored inside variables and can store properties with associated values – these properties define the behavior of the object within your code. Finally, Arrays are collections of data that can store any kind of data inside of them – they are simply lists of items stored within brackets (). All of these concepts build upon one another and understanding them is key to writing bug-free code that avoids DND errors.
