array-copyto
NOTE: array-copyto was renamed to @extra-array/copy.
Copy part of array to another array, like Array.slice().
Uses Array.length and Array.copyWithin() to improve performance.
Ref: Array copy loop vs copy within.
const copyTo = ;// copyTo(<array>, [begin=0], [end], [target=[]], [at], [till])// -> <target> ;// ['p', 'o', 'r', 't'];// ['o', 'r', 't'];// ['o', 'r'];// ['d', 'o', 'o', 'r'];// ['d', 'o', 'r']
