![]() ![]() An array containing the removed element (i.e., the last element) is returned. In the code below, colors.splice(-1,1,"gray") replaces the last element in the array colors with the value "gray". An array containing the removed element (i.e., the first element) is returned. In the code below, colors.splice(0,1,"gray") replaces the first element in the array colors with the value "gray". Example 7: Replacing an element with another element Example 7.1 An array containing these removed elements is returned. In the code below, colors.splice(0) removes all elements from the array colors because numElementsToDelete (the second argument) was not specified. Example 6: Removing all elements from an array In the code below, colors.splice(-3,2) removes two elements starting from the 3rd last position ("black") in the array colors. In the code below, colors.splice(1,2) removes two elements starting from the 2nd position from the array colors. Example 5: Removing two elements from an array Example 5.1 An array containing this removed element is returned. In the code below, colors.splice(-1,1) removes the last element ("purple") from the array colors. Example 4: Removing the last element from an array An empty array is returned since no elements were removed. In the code below, colors.splice(1,0) does not change the array at all since it removes 0 elements from the array. Example 3: Removing the second element from an array In the code below, colors.splice(1,1) removes the second element ("blue") from the array colors. Example 2: Removing the second element from an array In the code below, colors.splice(0,1) removes the first element ("red") from the array colors. Example 1: Removing the first element from an array. Also, don't forget to give each of these functions a unique name. I recommend creating separate functions to try out each of the examples below. So you have to copy and paste each of the code snippets below into a function before you run them. In Apps Script, you can only run functions. If no elements are deleted then the return value will be an empty array. One or more values to insert into the array.Īn array containing deleted values is returned by the splice() function. If this value is not specified or if it is greater than the number of elements after the start position, then all elements beyond the start position will be deleted. If this value is 0 or negative, no elements will be deleted. The number of elements to delete beginning at the starting point specified using the start parameter. This will be clear from the examples below. If it is negative, the starting position is determined by starting at the end of the array and moving towards the beginning of the array. If this value is greater than the length of the array, it will be set to the length of the array. The array index at which to splice the array. Syntax array.splice(start, numElementsToDelete, item1, item2, …itemN) Parameters How to create and run simple Apps Script scripts using the script editor in Google Sheets. What arrays are and how to use them in Apps Script. And you're equipped with a handy mnemonic, that splice compared to slice has an additional letter, 'p', which helps you remember that splice mutates and optionally adds or removes from the original array.This tutorial assumes that you're familiar with: You now know that slice makes a shallow copy of the original array, while splice mutates the original array and optionally adds or removes elements. ConclusionĪnd there we have it! This blog goes over the differences between slice and splice. And because splice can add and remove stuff to the original array, that means that it also mutates the original array. Because of the extra letter, I associate the additional letter to splice's use of adding or removing from the original array. splice has an extra letter, 'p', compared to slice. I remember the difference between slice and splice using a mnemonic. insert 'juliet' and 'zeke' at 3rd index // returns Ĭonsole. splice ( 3, 1, 'juliet', 'zeke' ) // remove 'harper'. ![]()
