I use one trick to remember things: the letter 'p' of the splice() referred to as permanently modifying the array.

I hope this post helps you clear the confusion between these two methods. The second argument represents the count. Takes 3 arguments, the last two arguments being optional, and the last argument can have any number of parameters (just remember that you don't have to pass it as an array type). Takes two arguments, both being optional. The result is not required to assign to a new variable. The result has to be assigned to a new array variable. This method is used to add/remove an item from the given array. This method is used to get a new array by selecting a sub-array of a given array. Slice () can fetch a new array from a sub-array of a given array while Splice() can add or remove items. In summary, the major differences are Slice () doesn’t modify the array while Splice () does. The following table illustrates the differences between slice vs splice Javascript. You can find out what's the main differences between these two methods below. Now we have a clear idea about how slice() and splice() methods work. And you can either assign the returned array to a variable or ignore it as you wish. The Javascript array splice is mainly used when you need to delete or add new elements to an array. Also, if you don't want to remove any items, you can simply add the second parameter as 0. When we add elements to the array, the array will grow in length. We can add any number of elements to the array by separating them by commas. And we added '🍏', '🍒' to the array where we remove the elements.We set the deleteCount as 1 since we want to remove only one element.Let favoriteFruits = let removedFruits = favoriteFruits. So what happens if we add a negative number as the start parameter? If the start is negative, it will count backward from the end of the array and remove the elements. Also, if you add any number higher than the largest index number of the array, it will not affect the original array. If you add 0 as the start parameter without any other parameters, it will remove everything from the array and change it to an empty array. And you can see the removed item in the array, removedFruits. Since we haven't specified a second parameter, it has removed everything after index 2, including the index 2 element. In the above example, we have added the start parameter as 2, and that's where it has started removing things from this array. You can check further details on these parameters below. The JS array splice method takes several arguments to decide which elements to delete, the delete count, and what elements to add. It will also return a new array with all the elements you have removed, which is helpful if you want to track what has been removed. This method modifies the array and does not create a new array. The splice() method in Javascript helps you add, update, and remove elements in an array. The slice() method is very useful for cloning an array, copying a portion of an array, and converting an array-like object into an array. This is very useful when you want to get the last element of the array, and then you just have to use -1. If we have given -2, it will return only. This will start counting from the end of the array and slice it (not the beginning from the array). In the above example, we have added a single argument as -3. Let favoriteFood = let slicedArray = favoriteFood. Also, If the arguments you pass are greater than the actual array, it will return an empty array. If you do not pass any arguments, the entire original array will be copied by default. The first argument is the startIndex, and the second is the endIndex. This method takes two optional arguments. Instead, it creates a new shallow copy of the original array. It does not modify or change the original array. The array slice javascript method copies a chunk (or slice) from an array and returns that copied part as a new array. I've put together this guide on these two methods so that you can slice and splice JavaScrips arrays like a pro. Javascript Slice() and splice() methods look similar, and they sound similar, so it's very easy to get confused and remember which is which. The two methods are among the most used array methods when it comes to adding, updating, or removing items in an array, and cloning an array or copying a portion of an array. Do you find yourself looking up the difference between javascript splice () and splice() methods all the time?
