Examples

Action desired	Example and result
Insert an element at the beginning of an array datum	`vars.$a=["a", "b", "c", "d"]; insertDatum(vars.$a, 1, 1, "z");` Returns: `vars.$a = {"z", "a", "b", "c", "d"}`
Insert an element in the middle of an array datum	`vars.$a=["a", "b", "c", "d"]; insertDatum(vars.$a, 3, 1, "z")` Returns: `vars.$a = {"a", "b", "z", "c", "d"}`
Insert an element at the end of an array datum	`vars.$a=["a", "b", "c", "d"]; insertDatum(vars.$a, 0, 1, "z");` Returns: `vars.$a = {"a", "b", "c", "d", "z"}`
To denull the array datum	`vars.$a=["a", "b", null, null, "e", "f", null, null, null, null]; insertDatum(vars.$a, 0, 1, "z");` Returns: `vars.$a = {"a", "b", , , "e", "f", "z"}`
To avoid denulling the array datum	`vars.$a=["a", "b", null, null, "e", "f", null, null, null, null]; insertDatum(vars.$a, 0, 1, "z", 0);` Returns: `vars.$a = {"a", "b", , , "e", "f", , , , ,"z"}`
To denull the array datum again	vars.$a=["a", "b", null, null, "e", "f", null, null, null, null]; insertDatum(vars.$a, 2, 1, "z"); Returns: `vars.$a = {"a", "z", "b", , , "e", "f"}`
