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 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. As a negative index, end indicates an offset from the end of the sequence. 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 Zero-based index at which to end extraction. If begin is undefined, slice begins from index 0. slice(-2) extracts the last two elements in the sequence. As a negative index, begin indicates an offset from the end of the sequence. slice(]) Parameters begin Zero-based index at which to begin extraction.
