@thi.ng/transducers/wrap-sides.d.ts

Collection of ~170 lightweight, composable transducers, reducers, generators, iterators for functional data transformations

/**
 * Yields iterator of `src` with the last `numLeft` values of `src`
 * prepended at the beginning and/or the first `numRight` values
 * appended at the end.
 *
 * @remarks
 * `numLeft` defaults to 1 and `numRight` defaults to same value as
 * `numLeft`, therefore wraps both sides by default and throws error if
 * either `nXXX < 0` or larger than `src.length`.
 *
 * See also:
 *
 * - {@link extendSides}
 * - {@link padSides}
 *
 * @param src -
 * @param numLeft -
 * @param numRight -
