The forEach method allow you to define parameters for which of the following? (Note: some of them are optional!)

The array you're iterating over

Which of the following accurately reflects how we might represent 2D data? Example data: a b c 1 2 3

var myData = [['a', 'b' ,'c'], [1, 2, 3]];

var myData = ['a', 1, 'b', 2, 'c', 3];

var myData = ['a', 'b', 'c', 1, 2 ,3];

var myData = ['a', 'b', 'c'] + [1, 2, 3];

4Which of the following accurately reflects how we might represent 2D data?

Example data:
a b c
1 2 3
1. Avar myData = [['a', 'b' ,'c'], [1, 2, 3]];
2. Bvar myData = ['a', 1, 'b', 2, 'c', 3];
3. Cvar myData = ['a', 'b', 'c', 1, 2 ,3];
4. Dvar myData = ['a', 'b', 'c'] + [1, 2, 3];
5In nested loops, the outer loop will be completed (i.e. iterate over every single item) before the inner loop ever begins.
