If you mean myArray, no it’s got the correct amount of braces.
It can get confusing looking at arrays like this one though.
to demonstrate, we can remove all the proper arrays with open and closing brackets.
if you take away the first 3 arrays in myarray, you’re left with the confusing part,
myArray=[[1,2,3], [4,5,6], [7,8,9], [[10,11,12], 13, 14]];
// first lets remove the matching pair of braces that enclose myArray, leaving just the values inside.
[1,2,3], [4,5,6], [7,8,9], [[10,11,12], 13, 14]
//[1,2,3], [4,5,6], [7,8,9] all open and close simply enough, so take those away,
// whats left is an array containing 1 array, and 2 numbers.
[ [10,11,12], 13, 14 ] // white space is for easy visualization of outer arrays brackets (dont actually code arrays with it)
Seems, you got it while I was making this visualization. I probably would have confused you more anyway
