Function movingWindow

Creates a moving window

// Create a moving window of 3 samples
const window = movingWindow(3);

window(1); // [ 1 ]
window(2); // [ 1, 2 ]
window(3); // [ 1, 2, 3 ]
window(4); // [ 2, 3, 4 ]
Copy

'reject' option allows values to be discarded:

// Reject all NaN values
const window = movingWindow({ samples: 3, reject: (v) => Number.isNaN(v) });
Copy

'allow' is similar, but is applied after 'reject' (if provided). Instead, values must pass true

If a reject/disallow is triggered, the current state of the queue is returned.
