new SliceLens(i, j) → {SliceLens}
A SliceLens focuses on a slice of an array from starting and ending indices.
SliceLenses can be constructed in two ways:
- By giving it integer start and end indices, which can be negative (negative indices start from the right)
- By passing in a Python-style string representing the slice, e.g. '0:-1'. By default, the starting index is set to 0 and the ending index is set to arr.length, so for instance, new SliceLens(':') focuses on the whole list.
Parameters:
| Name | Type | Description |
|---|---|---|
i |
int | string | The start of the slice or a string representing the slice, e.g. '0:-1" |
j |
int | The end of the Slice |
Returns:
- Type
- SliceLens
