Package Exports
- @writetome51/array-insert-at
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@writetome51/array-insert-at) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
insertAt<T>(
index,
values: T[],
array: T[]
): void
At index, values are inserted in array.index can be negative or positive. If positive, existing items beginning at that index
will be pushed to the right to make room. If negative, existing items ending at that
index will be pushed to the left to make room. No items get removed.
Examples
let arr = [1,2,3,4];
insertAt(2, [7, 8], arr);
// arr is now [1,2,7,8,3,4]
let arr = [1,2,3,4];
insertAt(-1, [7, 8], arr);
// arr is now [1,2,3,4,7,8]
let arr = [1,2,3,4];
insertAt(-4, [7, 8], arr);
// arr is now [1,7,8,2,3,4]Installation
