I have been reading online and some places say it isn't possible, some say it is and then give an example and others refute the example, etc.
How do I declare a 2 dimensional array in JavaScript? (assuming it's possible)
How would I access its members? (myArray[0][1] or myArray[0,1]?)

Assuming a somewhat pedantic definition, it is technically impossible to create a 2d array in javascript. But you can create an array of arrays, which is tantamount to the same. FYI... when you fill an array with more arrays using var arr2D = new Array(5).
The two-dimensional array is a collection of items which share a common name and they are organized as a matrix in the form of rows and columns. The two-dimensional array is an array of arrays, so we create an array of one-dimensional array objects.
var items = [ [1, 2], [3, 4], [5, 6] ]; console.log(items[0][0]); // 1 console.log(items[0][1]); // 2 console.log(items[1][0]); // 3 console.log(items[1][1]); // 4 console.log(items);You simply make each item within the array an array.
var x = new Array(10); for (var i = 0; i < x.length; i++) { x[i] = new Array(3); } console.log(x);If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
