Replaces adjacent items in the array with same number of new adjacent items
npm install @writetome51/array-replace-adjacent-atReplaces adjacent items, beginning at startingIndex, with the same number
of newValues, in array. index can be negative or positive.
js
let arr = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];replaceAdjacentAt(0, [20], arr);
// arr is now [ 20, 2, 3, 4, 5, 6, 7, 8, 9, 10 ]
replaceAdjacentAt(0, [30, 31, 32, 33], arr);
// arr is now [ 30, 31, 32, 33, 5, 6, 7, 8, 9, 10 ]
replaceAdjacentAt(-3, [1, 2, 3], arr);
// arr is now [ 30, 31, 32, 33, 5, 6, 7, 1, 2, 3 ]
// This works because the second arg has length greater than zero:
replaceAdjacentAt(-3, 'aaa', arr);
// arr is now [ 30, 31, 32, 33, 5, 6, 7, 'a', 'a', 'a' ]
// This errors because the second arg has length of zero:
replaceAdjacentAt(0, [], arr);
// Error: 'Input must be integer greater than zero'
// This errors because arr only has 2 items left at index 8:
replaceAdjacentAt(8, ['a', 'b', 'c'], arr);
// Error: 'the array does not have enough items to fulfill your request'
