JavaScript Array slice() method : The slice() method is used to get the elements between two position. The slice() method returns the array of extracted elements. It doesn't change the original array. The index starts from 0.
Syntax of the Array slice() method :
array.slice(start,end)
start : Required. This is the numeric value from where to start the extract elements. To count from end use the negative value.
end : Optional. This is the numeric value where end the extraction. It will omit the last value.
Example of Array slice() method : Here I will show how to extract the elements between two indexes of the array. The first sample will extract all the elements starts from 2nd position to end.
