Write a piece of JavaScript that defines a function named s
that
x
,
y
, t
(x
and y
less than 16).
The source code defining s
will be visually displayed on a 16x16
grid. 32 times a second, it will be separately called for each x
,
y
coordinate of the grid, initially with a t
parameter
equal to 0, and incrementing by one with each series of calls.
The result of each call to s
will determine the shade of the
character in the corresponding grid location.
var step = 0 _frame = function() { for (var row = 0; row < 16; row++) { for (var column = 0; column < 16; column++) { var shade = s(row, column, step) var cell = display.children[row].children[column] cell.style.color = `rgb(${shade}, ${shade}, ${shade})` } } step++ } setInterval(_frame, 31.25)
