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. The function returns a new array containing the copied values.Start – start parameter is an optional parameter, which is used to specify the starting index from where the elements start to be extracted. If end is greater than the sequence length, slice extracts through to the end of the sequence.For example, slice(1,-1) extracts the first element through the second-to-last element in the sequence. If negative, it extracts until the end of the sequence.If not supplied, it extracts to the end of the sequence.end (optional) : The ending index of the copied array.If start is greater than the index range of the sequence, an empty array is returned.For example, slice(-2) extracts the last two elements in the sequence. If negative, it indicates an offset from the end of the sequence.If not supplied, it starts from index 0.
start (optional): The starting index of the copied array.The slice() method takes the following parameters: It saves this copied portion into a new array but does not modify the original array. The slice() method in JavaScript returns a shallow copy of an array’s selected portion.
