Please provide a link to the lesson.
In an Array you have 1 or more element's with a certain Value.
The VALUE can be anything from:
•Number •String •Boolean •Symbol •Object ◦Function ◦Array ◦Date ◦RegExp ◦Math •Null •Undefined
In an Array of Arrays
the element's have a Array Value
var arrayOne = [ ["arr2_elem0","arr2_elem1"] , ["arr3_elem0","arr3_elem1"] ]
=arrayOne= is an Array which has 2 element's
To =access= an _Array-element you use the so-called =bracket-notation=
arrayOne --> an Array-Value ["arr2_elem0","arr2_elem1"] arrayOne --> a String-Value "arr2_elem0"
You are able to use a =double-FOR-loop= to get =access= to all the Value's

Looks like @leonhard.wettengmx.n gave a great description of an array and an array of other data types.
The question asks you to create an array with 3 rows and 3 columns, similar to the example where they show an array with 2 rows and 2 columns.
Does this help?
Maybe this helps....
