Let us see an example belowĭocument.write('The given array is as follows :' + arr )ĭocument.write('The sliced array is as follows : ' + arr.slice() ) Įxplanation: In the above program, we saw that we are using a slice() method where there are no parameters, so it will print all the elements in the given array as a new array that has the same elements as the original array. Cloning in javascript means copying object properties to another object to avoid creating an existing object. The slice() method is used to clone an array. We will see in the below article regarding the uses of the slice() form on array in javascript. In the above statement, we can see the start parameter has index 1, and the end parameter has index 3, which says it will select the second and third element from the given array. The statement article.slice(1,3) indicates that the array named “article” consists of 5 elements, and the indexing of the array starts from 0. In the above program, we select the second and third elements of the given array using the slice() method.

Var article = ĭocument.getElementById('arr_slice').innerHTML = heading Example #1Ĭlick the button below to select the second and the third elements from the array and print. In other words, it will consider the length or size of the array as the value for the end parameter. If the end parameter is not specified when using the slice() method, it will default to extracting elements up to end-1. Therefore, this start parameter identifies the zero-based index of the array. This method returns a new array that contains the selected elements of the array. end: On the other hand, the end parameter is used to define the index of the array where the slice() method should stop extracting elements.It determines the starting point of the selection process. start: The start parameter is used to specify the index of the array from which the slice() method should begin selecting elements.
