In the above code the parameter passed to the slice( ) method is for start index as 1 and end index 4, so the slice( ) method slice the given array a or extract the elements of the given array from index 1 to index 3 (the end value is excluding). In the next example code, we will rewrite the above code for slice( ) method to extract the multiple elements from the given array. Hence in an array an at the index 2 it stores element “Orange”, So the return value of the slice method is “Orange”, as shown in the output. In the above code the slice( ) method is using and the passed the parameter value for start index as 2 and end index 3, so the slice( ) method slice the given array a or extract the elements of the given array from index 2 to index 2 (the end value is excluding). Next, we will write the HTML code to understand the slice( ) method more clearly with the following example, the slice( ) method used to extract the single element from the array a bypassing the start index as 2 and end index 3.

If we do not provide a value for this parameter, then the function takes the length of the array as the default value and if the end value is greater than the array length, then the end value takes as the length of the array. Note that the end index value is excluding means that the end value will be end-1value. If we do not provide a value for this parameter, then the function takes 0 as default value.Įnd – end parameter is an optional parameter, which is used to specify the ending index up to where the elements to be extracted. Learn more, come to the planet, the meaning of the existence of this planet only one: is to learn.Start – start parameter is an optional parameter, which is used to specify the starting index from where the elements start to be extracted.
