This is what the result would look like in the console. Since we are not deleting any items, our delete count is zero. The first number is the starting index, and the second number is the delete count. If we wanted to add another food item to the array at index 1, then we can use the following code: food.splice(1,0,"burrito") In this example, we have an array of food items. splice(start, optional delete count, optional items to add) If nothing was removed from the array, then the return value will just be an empty array. The splice() method is used to add or remove elements of an existing array and the return value will be the removed items from the array. Unlike the slice() method, the splice() method will change the contents of the original array. const cities = Ĭonst newCityArr = cities.slice(2,4) How to use the splice() JavaScript array method The new returned array will only include the cities at index 2 and 3 because the end position is not included in the extracted elements. In this example, we have specified a start index of 2 and end index of 4. The end position will not be included in the extracted elements for the new array. If an end position is specified, then the slice() method will extract elements from the start position up to the end position. const newCityArr = cities.slice(5) How to use the slice() JavaScript method using the start and end parameters If the start parameter is greater than the last index of the array, then an empty array will be returned. In this example, we will set the start position at -2 which will select the last two cities in the array and return them in a new array. You can also use negative indexes which will start extracting elements from the end of the array. The original array was not modified as we can see here in this example. In this example, we will set the start position at index 2 which will select the last three cities in the array and return them in a new array. It is important to remember that arrays are zero based indexed. You can use the optional start parameter to set a starting position for selecting elements from the array. How to use the slice() JavaScript method using the start parameter When I console.log the result, then I will see all of the elements from my cities array copied into this new array. I can use the slice() method to create a shallow copy of that array. In this first example, I have created a list of cities from around the world. How to use the slice() JavaScript method without the start and end parameters Let's take a look at some examples to better understand how the slice() method works. Here is the basic syntax: slice(optional start parameter, optional end parameter) It is important to note that the slice() method does not alter the original array but instead creates a shallow copy. The slice() method can be used to create a copy of an array or return a portion of an array. How to use the slice() JavaScript array method In this article, I will walk you through how to use the slice() and splice() array methods using code examples. I bet they were thinking they had the new Frankenstein on their hands.When you are first learning JavaScript, it might be difficult to know the difference between the slice() and splice() array methods. I literally laughed out loud when he started fucking Dren, and shook my head when they had her getting raped at the end. The film had potential, but ended up being a cookie cutter film that showed how inexperienced two of the three writers were. It was as if the writers decided to let the main female character be the one with no morals, only to reel the audience in at the end and show that not all women are crazy. Oh, and I don't know any film (probably no one in real life, either) where the head of a pharmaceutical company would be empathetic to someone holding potentially billions of dollars in her belly, and telling her if she didn't want to go through with it, she didn't have to. The third act was slow, building up to the last eight minutes of the film, which felt too rushed. I think that Brody's character's arc was absurd, it defied all logic and reason. They only hinted at her terrible childhood, and should have used the first and second acts to flesh this part of her character out, instead of having her do insane things, when her character was still only two dimensional. I thought that the entire reason for Sarah Polley's character to be irresponsible and, to a degree, batshit crazy, was weak. I thought it was about the most predictable piece of film that I have ever seen. And people'd be, like, "There he goes homeboy fucked a Martian once." I'd be the first motherfucker to see a new galaxy, or find a new alien life form. After watching it, I was reminded of this line:
