Array element assignment

Replace the content of one array with the content of another array. Assume that: • alternative approaches are not a choice: • reusing the second array; • cloning the second array; • the arrays are not the same, are not sparse and are of the same length; • content order must be kept; • the difference between +0 and -0 and the differences between NaNs are irrelevant: • we can use === or Object.is() to avoid assignments; • otherwise, elements are opaque; The tests with literals, constants and variables serve as baselines for performance comparison.
