arrayĪrray.splice(2, 0, 'newEl') // returns įor both slice() and splice(), a negative value can be passed as an index value to change the content starting from the last position. It takes one optional argument, as a character, on which to split. If passed only 1 argument, it removes rest of the elements starting with the index passed in as argument.Īrray.splice(3) // returns Īrray.splice(2, 6) // returns Īrray.splice(2, 1, 'newEl') // returns split() method in JavaScript is used to convert a string to an array. ex:Ĭonst array = Īrray.slice(2, 6) // returns: Īrray.slice(2) // returns: Ĭan change the content of an array by adding, removing, or replacing the existing element of it. If pass only 1 argument, it returns all items starting at the argument passed in. String.split(' ') // returns: Ĭan be used on strings and arrays returns a string (if used on a string) or array (if used on an array) with items starting at first argument as the starting index up to (not including) the second argument passed in.

If you're in the same situation, this may help: Use,Ĭan be used on strings and returns an array of divided strings by what passed in as the argument. If you do not specify any elements, splice() will only remove elements from the array.When I started using JS methods it took me a while to get familiar and memorize the difference between the 3S and where I can get good use of split, slice, and splice. The split () method splits (divides) a string into two or more substrings depending on a splitter (or divider). If omitted, an array with the original string is. A string or regular expression to use for splitting. This method selects the elements starting from the given start argument, and ends at, but excluding the given end argument. The split () method returns the new array. Javascript splice () method Javascript slice () method We will describe the above methods in detail below: Javascript slice () method: This method returns a new array containing the selected elements. Misalnya jika kita ingin mendapatkan subarray antara indeks 2 dan 5 kita akan menulis. Ini adalah setup untuk slice (): ' arr.slice (start, end)' atau 'arr.slice (start)'. Ini mengembalikan salinan larik atau string antara dua indeks dan TIDAK mengubah larik atau string asli.

The elements to add to the array, beginning from start. The split () method splits a string into an array of substrings. Metode JavaScript ini dapat digunakan pada array dan string. 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. 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.Zero-based index at which to start changing the array, converted to an integer.
