split (Lodash compatibility)

Use JavaScript's String.prototype.split

This split function operates slowly due to handling null or undefined.

Instead, use the faster and more modern JavaScript's String.prototype.split.

Splits a string into an array using a separator.

const segments = split(str, separator);

Reference

split(string, separator?, limit?)

Use split when you want to divide a string into an array using a specific separator. You can also limit the maximum length of the resulting array.

import { split } from 'es-toolkit/compat';

// Split by hyphen
split('a-b-c', '-');
// Returns: ['a', 'b', 'c']

// Limit the number of results
split('a-b-c-d', '-', 2);
// Returns: ['a', 'b']

// Split by regular expression
split('hello world', /\s/);
// Returns: ['hello', 'world']

If no separator is specified, the entire string becomes the first element of the array.

import { split } from 'es-toolkit/compat';

split('hello');
// Returns: ['hello']

null or undefined are treated as empty strings.

import { split } from 'es-toolkit/compat';

split(null);
// Returns: ['']

split(undefined);
// Returns: ['']

Parameters

• string (string, optional): The string to split. Defaults to an empty string.
• separator (RegExp | string, optional): The separator to use for splitting.
• limit (number, optional): The maximum length of the resulting array.

Returns

(string[]): Returns an array of strings split by the separator.
