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?
