As we can see in the example below, the item at the 5th position ( Kiwi) is not included in the output array( my_fav_fruits). Slice Fact 2: The item at the end position is not included in the new array. The new array is often referred as a shallow copy of the original array which we will discuss later in the article. The newly formed array assigned to my_fav_fruits variable is just a copy of a portion of the original array fruits. Slice Fact 1: The original array is not modified. Now that we have seen a basic example, let's discuss some of the facts related to the method. Which portion it returns is decided by two optional parameters begin and end.Īrr.slice(]) let fruits = The Slice method returns a portion of an array into a new array. Just note that most of the discussion and examples are going to be about Array.Slice() method.

It will either return a sub-string or a sub-array. The method's behavior is almost same in both the cases. To get into details of what Strings and Arrays are in Javascript is beyond the scope of this article. However the 'slice()' method can be applied to them tooĪrray samples //Examples of Arrays in Javascript The following are 'strings' but not 'String objects' Let str_spcl_chars = new str_zeros = new String('000000')

Let str_greet = new String('Hey! Developers') String samples //Examples of String Objects in Javascript In technical terms, the slice() method can be applied to two types of objects in Javascript: Strings and Arrays. There are two types of things(more appropriately called objects) which we can get a slice of. What are the things we can get a slice of? In this article we will discuss what are those things, how do we slice them and a few other aspects of the slice() method. All that slice() method does is get us a slice(a portion) of things. And its definitely for you if you thought there couldn't be an 2500+ words article merely on slice() method.If you have used it earlier and have been planning to get a deeper understanding of it.If you have copied and pasted a chunk of code from stackoverflow which had slice() method but didn't understand the code completely.
