🌚 Add few items at the end of array: const arr = arr.splice(arr.length, 0, '🌕', '🌞', '🌦') // console. 🌚 You can specify 0 as the number of items to remove to simply add new items at the specified location in the array: const arr = arr.splice(2, 0, '⭐️', '💥') // console.log(myArr) // For example, str.slice (1, 4) extracts the second character through the fourth character (characters indexed 1, 2, and 3 ).

slice () extracts up to but not including inde圎nd. Changes to the text in one string do not affect the other string. 🌚 Remove 1 element from index -2: const arr = arr.splice(-2, 1) // console.log(myArr) // slice () extracts the text from one string and returns a new string. 🌚 An arbitrary amount of additional arguments can be passed-in and will be added to the array: const arr = arr.splice(2, 1, '⭐️', '💥') // console.log(myArr) // 🌚 Remove 1 element at index 3: const arr = arr.splice(3, 1) // console.log(myArr) // 🌚 When only one argument is provided, all the items after the provided starting index are removed from the array: const arr = arr.splice(2) // console.log(myArr) // NOTE: Splice always returns an array containing the deleted elements.

In item, The number you want to add( If you're removing, you can just leave this blank). In deleteCount, The number of items you want to remove. If start is negative, it will begin that many elements from the end of the array. If start is greater than the length of the array, then start will be set to the length of the array. Start specifies index at which to start changing the array. Syntax: let arrDeletedItems = array.splice(start]]])

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. Note: As compared to the slice() method which. The following table illustrates the differences between slice vs splice Javascript. const arr = arr.splice(2,3) // console.log(myArr) // The JavaScript splice() method changes the elements of the array by replacing or removing the elements, in place. The splice method changes the content of the array in place and can be used to add or remove items from the array.
