replaceBetween(      numItemsToPreserveAtEachEnd,      newValues,      array): void

Replaces everything between numItemsToPreserveAtEachEnd with newValues in array.

Examples

let arr = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
replaceBetween(3, [100], arr);
// arr is now [ 1, 2, 3, 100, 8, 9, 10]

arr = [1, 2, 3, 4, 5];
replaceBetween(1, [20, 30], arr);
// arr is now [1, 20, 30, 5]

// You can replace something with nothing. Example:

arr = [ 1, 2, 3, 4, 5, 6 ];
replaceBetween(2, [], arr);
// arr is now [ 1, 2, 5, 6 ]
