We can also use the concise and precise interval notation to describe a range of values.
[,]=> inclusion(,)=> exclusion
For example, we can say, "Math.random()returns a random number in the interval[0, 1)"

You missed one.
And what's the total number of function calls?

When does the function return null?

How do you figure it is [0, 1] and not [0, 1)?

That still does not indicate how many function calls? And the answer is not 3.

What does the function return when the user does not enter anything and click the "OK" button? null or an empty string ""?
When does the function return null?

I was under the impression that AI tools should be avoided and that we should instead ask other trainees and volunteers, as well as use Google. |

Not at all. Asking AI is not much different from asking volunteers or using Google search. You just need to validate the answer and make sure you truly understand the answer (to the point that you can reproduce the solution or explain the solution).
AI is here to stay, and knowing how to use it as a tool to find answer and solve problem is a critical skill to flourish in the IT field.
Why don't you try your question (in the PR description) on AI. If you present your answer here, I will share my view with you.
Changes look good. I will mark this as "Complete" first.
| If the user has entered text, the return value is a string containing the entered text. | ||
| If the user leaves the text field blank and clicks the OK button, the return value is an empty string. | ||
| If the user enters a name or leaves the text field blank but clicks the Cancel button, the return value is null. |

This is accurate but could be simplified. Some of the info is not very useful.
Knowing how to explain or describe code is an important skill in software development.
Suggestion: Use AI to help you figure out how to make the description more concise.

I answered all the questions in the
.jsand.mdfilesQuestions
According to the console in the Web Inspector (Safari) or JavaScript Console (Chrome),
NumberandStringand other types are "function" which confuses me because I expected them to be classified asObject.In Swift programming language,
String,Int,Double, etc. arestructtype and notfunction.Why are
functions that belong to anObjectare calledfunction? Why not calledmethod? That's how it is in Swift. Functions are freestanding and belong to no objects, struct, etc.
