split()

Learn how to use the split() function to split the source string according to a given delimiter.

The split() function takes a string and splits it into substrings based on a specified delimiter, returning the substrings in an array. Optionally, you can retrieve a specific substring by specifying its index.

Syntax

split(source, delimiter [, requestedIndex])

Parameters

Name	Type	Required	Description
source	`string`	✔️	The source string that is split according to the given delimiter.
delimiter	`string`	✔️	The delimiter that will be used in order to split the source string.
requestedIndex	`int`		A zero-based index. If provided, the returned string array contains the requested substring at the index if it exists.

Returns

An array of substrings obtained by separating the source string by the specified delimiter, or a single substring at the specified requestedIndex.

Examples

print
    split("aa_bb", "_"),           // ["aa","bb"]
    split("aaa_bbb_ccc", "_", 1),  // ["bbb"]
    split("", "_"),                // [""]
    split("a__b", "_"),            // ["a","","b"]
    split("aabbcc", "bb")          // ["aa","cc"]

print_0	print_1	print_2	print_3	print4
[“aa”,“bb”]	[“bbb”]	[""]	[“a”,"",“b”]	[“aa”,“cc”]
