![]() ![]() 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 deleteCount is 0 or negative, no elements are removed. 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. 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. If nothing was removed from the array, then the return value will just be an empty array. Array elements which do not pass the callbackFn test are not included in the new array. It calls a provided callbackFn function once for each element in an array, and constructs a new array of all the values for which callbackFn returns a truthy value. ![]() 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. 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. Description The filter () method is an iterative method. 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.Alternative of Array splice () method in JavaScript 2. Zero-based index at which to start changing the array, converted to an integer.
