![]() If you do not specify any elements, splice() will only remove elements from the array. ![]() The elements to add to the array, beginning from start. ![]() In this case, you should specify at least one new element (see below). If the sliced portion is sparse, the returned array is sparse as well. The slice () method preserves empty slots. If deleteCount is 0 or negative, no elements are removed. It does not alter this but instead returns a shallow copy that contains some of the same elements as the ones from the original array. The slice() method selects the elements starting at the given start. However, if you wish to pass any itemN parameter, you should pass Infinity as deleteCount to delete all elements after start, because an explicit undefined gets converted to 0. The slice() method returns the selected elements in an array, as a new array object. If deleteCount is omitted, or if its value is greater than or equal to the number of elements after the position specified by start, then all the elements from start to the end of the array will be deleted. This is different from passing undefined, which is converted to 0.Īn integer indicating the number of elements in the array to remove from start. If start is omitted (and splice() is called with no arguments), nothing is deleted.Negative index counts back from the end of the array - if start = array.length, no element will be deleted, but the method will behave as an adding function, adding as many elements as provided.You need to set the type of the exercises. exercises have type any and you can not call. Destructuring the props like this is causing the issue. Zero-based index at which to start changing the array, converted to an integer.
