17+
value: any
18+
Inserting value.
19+
20+
Returns

{{alias}}.assign( x, index, value, out, stride, offset )
37+
Copies elements from one array to another array and inserts the element at the
38+
specified index to a provided value.
39+
40+
Negative indices are resolved relative to the last array element, with the
41+
last element corresponding to `-1`.
42+
43+
Parameters
44+
