Both include a reference to the object myHonda.

In the following example, slice creates a new array, newCar, from m圜ar. Examples Return a portion of an existing array Using slice If a new element is added to either array, the other array is not affected. Changes to the string, number or boolean in one array do not affect the other array. For strings, numbers and booleans (not String, Number and Boolean objects), slice copies the values into the new array.If a referenced object changes, the changes are visible to both the new and original arrays. Both the original and new array refer to the same object. For object references (and not the actual object), slice copies object references into the new array.Elements of the original array are copied into the returned array as follows: It returns a shallow copy of elements from the original array. Return valueĪ new array containing the extracted elements. If end is greater than the length of the sequence, slice extracts through to the end of the sequence ( arr.length). If end is omitted, slice extracts through the end of the sequence ( arr.length). slice(2,-1) extracts the third element through the second-to-last element in the sequence. A negative index can be used, indicating an offset from the end of the sequence. For example, slice(1,4) extracts the second element through the fourth element (elements indexed 1, 2, and 3). slice extracts up to but not including end. end Optional Zero-based index before which to end extraction. If begin is greater than the length of the sequence, an empty array is returned.

If begin is undefined, slice begins from index 0. slice(-2) extracts the last two elements in the sequence. Parameters begin Optional Zero-based index at which to begin extraction. If you'd like to contribute to the interactive demo project, please clone and send us a pull request.
