Function spliceArray2DMajor

splice rows of a row-major 2D array and optionally insert new rows at the specified start index.

Example

delete 1 row from arr2d (starting at row-index 1), and insert 2 new rows in its place.

const arr2d: Array2DRowMajor<number> = [
	[1 , 2 , 3 , 4 , 5 ],
	[6 , 7 , 8 , 9 , 10],
	[11, 12, 13, 14, 15],
]
const deleted_rows = spliceArray2DMajor(arr2d, 1, 1,
	[21, 22, 23, 24, 25],
	[31, 32, 33, 34, 35]
)
arr2d === [
	[1 , 2 , 3 , 4 , 5 ],
	[21, 22, 23, 24, 25],
	[31, 32, 33, 34, 35],
	[11, 12, 13, 14, 15],
]
deleted_rows === [
	[6 , 7 , 8 , 9 , 10],
]

  • Type Parameters

    • T

    Parameters

    • arr2d: Array2DRowMajor<T>

      the row-major 2D array to be spliced.

    • start: number

      the row-index at which to start changing the array.

    • Optionaldelete_count: number

      the number of rows to remove. if undefined, all rows from start to the end of the array will be removed.

    • Rest...insert_items: Array2DRowMajor<T>

      optionally insert row-major based 2D array items the index of start.

    Returns Array2DRowMajor<T>

    a new row-major 2D array containing the deleted rows.
