module.exports ⇒ Array ⏏

The slice() method returns a shallow copy of a portion of an array into a new array object selected from begin to end (end not included). The original array will not be modified.

Kind: Exported member
Returns: Array - A new array containing the extracted elements.

Param	Type	Description
array	Array | Object	The array to slice.
[start]	number	Zero-based index at which to begin extraction. A negative index can be used, indicating an offset from the end of the sequence. slice(-2) extracts the last two elements in the sequence. If begin is undefined, slice begins from index 0.
[end]	number	Zero-based index before which to end extraction. Slice extracts up to but not including end. For example, slice(1,4) extracts the second element through the fourth element (elements indexed 1, 2, and 3). A negative index can be used, indicating an offset from the end of the sequence. slice(2,-1) extracts the third element through the second-to-last element in the sequence. If end is omitted, slice extracts through the end of the sequence (arr.length). If end is greater than the length of the sequence, slice extracts through the end of the sequence (arr.length).

Example

var slice = require('array-slice-x');
var fruits = ['Banana', 'Orange', 'Lemon', 'Apple', 'Mango'];
var citrus = slice(fruits, 1, 3);

// fruits contains ['Banana', 'Orange', 'Lemon', 'Apple', 'Mango']
// citrus contains ['Orange','Lemon']
