/**

 * @ngModule CommonModule

 * @whatItDoes Creates a new List or String containing a subset (slice) of the elements.

 * @howToUse `array_or_string_expression | slice:start[:end]`

 * @description

 *

 * Where the input expression is a `List` or `String`, and:

 * - `start`: The starting index of the subset to return.

 *   - **a positive integer**: return the item at `start` index and all items after

 *     in the list or string expression.

 *   - **a negative integer**: return the item at `start` index from the end and all items after

 *     in the list or string expression.

 *   - **if positive and greater than the size of the expression**: return an empty list or string.

 *   - **if negative and greater than the size of the expression**: return entire list or string.

 * - `end`: The ending index of the subset to return.

 *   - **omitted**: return all items until the end.

 *   - **if positive**: return all items before `end` index of the list or string.

 *   - **if negative**: return all items before `end` index from the end of the list or string.

 *

 * All behavior is based on the expected behavior of the JavaScript API `Array.prototype.slice()`

 * and `String.prototype.slice()`.

 *

 * When operating on a [List], the returned list is always a copy even when all

 * the elements are being returned.

 *

 * When operating on a blank value, the pipe returns the blank value.

 *

 * ## List Example

 *

 * This `ngFor` example:

 *

 * {@example common/pipes/ts/slice_pipe.ts region='SlicePipe_list'}

 *

 * produces the following:

 *

 *     <li>b</li>

 *     <li>c</li>

 *

 * ## String Examples

 *

 * {@example common/pipes/ts/slice_pipe.ts region='SlicePipe_string'}

 *

 * @stable
