paramater "arr" under function buildList() question

function BuildList(arr) { ... }

referring to Dave's code, what is the value of the parameter 'arr'? Will it depend on the correct or wrong answers? If not can you please tell me what is the value for the arr? Thank you so much.

Hi Mariella, the parameter 'arr' is like a variable you create when declaring the 'BuildList' function. When you call the function you pass in an argument into it. That argument is like the value which is stored in a variable(the 'arr' parameter). From what I can recall about this particular course, the 'BuildList' function has an 'arr' parameter which represents an array of correct/wrong answers. So depending on what array you pass into the function when calling it, will determine the value of 'arr'.
