// Arrays 3: Our first array

// Creating a basic array with 1000 elements

​

// In this sketch we have 1000 instances of the same thing.

// We can't write each one out one at a time.

// Let's make an array.

​

​

// Create a new array.

// The name of the array is 'x'

// The number of elements in the array is 1000.

let x = new Array(1000);

​

// Hit play and see what happens... 

// ... For now we're going to move to the next couple of sketches

// and then come back to this one in sketch 4.6_arrays_6
