A script is any computer program that automates the execution of tasks for a particular runtime environment. Which of the following represent elements of a well-written script? (Select all that apply.)A.ParametersB.Branching and loopingC.Unexpected checksD.Unit tests

All of the options represent elements of a well-written script.

A. Parameters: These are important as they allow scripts to be more flexible and reusable. They can be used to input different data without changing the script itself.

B. Branching and looping: These are fundamental control structures in programming. Branching allows a script to make decisions and perform different actions depending on certain conditions. Looping allows a script to perform a certain action multiple times.

C. Unexpected checks: These are also known as error checks. They are important to ensure that the script can handle unexpected situations or inputs without crashing or producing incorrect results.

D. Unit tests: These are used to check that individual parts of the script work as expected. They are a key part of maintaining code quality and making sure that changes or additions to the script don't break existing functionality.
