Description. The split() method splits a string into an array of substrings. The split() method returns the new array. The split() method does not change the original string. If (" ") is used as separator, the string is split between words.

The split() method of String values takes a pattern and divides this string into an ordered list of substrings by searching for the pattern, puts these substrings into an array, and returns the array.
Parameters
separator The pattern describing where each split should occur. Can be undefined, a string, or an object with a Symbol.split method — the typical example being a regular expression. Omitting separator or passing undefined causes split() to return an array with the calling string as a single element. All values that are not undefined or objects with a @@split method are coerced to strings. limit Optional A non-negative integer specifying a limit on the number of substrings to be included in the array. If provided, splits the string at each occurrence of the specified separator, but stops when limit entries have been placed in the array. Any leftover text is not included in the array at all. •The array may contain fewer entries than limit if the end of the string is reached before the limit is reached. •If limit is 0, [] is returned.
Return value
An Array of strings, split at each point where the separator occurs in the given string.
If separator is a non-empty string, the target string is split by all matches of the separator without including separator in the results. For example, a string containing tab separated values (TSV) could be parsed by passing a tab character as the separator, like myString.split("\t"). If separator contains multiple characters, that entire character sequence must be found in order to split. If separator appears at the beginning (or end) of the string, it still has the effect of splitting, resulting in an empty (i.e. zero length) string appearing at the first (or last) position of the returned array. If separator does not occur in str, the returned array contains one element consisting of the entire string.
If separator is an empty string (""), str is converted to an array of each of its UTF-16 "characters", without empty strings on either ends of the resulting string.
If separator is a regexp that matches empty strings, whether the match is split by UTF-16 code units or Unicode code points depends on if the regex is Unicode-aware.
If separator is a regular expression with capturing groups, then each time separator matches, the captured groups (including any undefined results) are spliced into the output array. This behavior is specified by the regexp's Symbol.split method.
If separator is an object with a Symbol.split method, that method is called with the target string and limit as arguments, and this set to the object. Its return value becomes the return value of split.
Any other value will be coerced to a string before being used as separator.
Using split()
When the string is empty and a non-empty separator is specified, split() returns [""]. If the string and separator are both empty strings, an empty array is returned. The following example defines a function that splits a string into an array of strings using separator. After splitting the string, the function logs messages indicating the original string (before the split), the separator used, the number of elements in the array, and the individual array elements. This example produces the following output:
Removing spaces from a string
In the following example, split() looks for zero or more spaces, followed by a semicolon, followed by zero or more spaces—and, when found, removes the spaces and the semicolon from the string. nameList is the array returned as a result of split(). This logs two lines; the first line logs the original string, and the second line logs the resulting array.
Returning a limited number of splits
In the following example, split() looks for spaces in a string and returns the first 3 splits that it finds.

Split.js is a lightweight and flexible JavaScript library for creating resizable split views. It supports horizontal and vertical layouts, touch events, and custom gutters.
Introduction to the JavaScript String split() method. The String.prototype.split() divides a string into an array of substrings: split([separator, [,limit]]); Code language: JavaScript (javascript) The split() accepts two optional parameters: separator and limit.

5 mar 2013 · Il Metodo Split in JavaScript consente di dividere il contenuto di una stringa in due variabili, divise per il valore definito come Split. Ad esempio, in una serie di numeri da 1 a 9, dividendo il contenuto con il metodo split a valore 5 si ottengono 2 stringhe, la prima delle quali va da 1 a 4 (1234) mentre la seconda da 6 a 9 (6789).
16 giu 2021 · The split() method splits (divides) a string into two or more substrings depending on a splitter (or divider). The splitter can be a single character, another string, or a regular expression. After splitting the string into multiple substrings, the split() method puts them in an array and returns it.
