What is string.split and how do you use it?

Hello!
string.split is a function that gives parts of a string separated by the character/pattern you give it!
For example, let's say we had a string named "Hello Everyone!" to the variable String
Now we are going to split the string by the separator or called delimiter.
local String = "Hello Everyone!"
string.split(String, " ")
Would this do anything? It wouldn't.
string.split returns a array, or a table with only numerical indexes.
-- Arrays
local Array = {
1, -- If you dont provide a index, it'd default to 1!
2, -- Index 2
"Hello!" -- Index 3
}, or
local Array = {
[1] = "Hello, this is the first index!"
}
-- This is NOT a array:
local Dictionary = {
KeyOne = "ValueOne", -- Index "KeyOne" (Notice how its not a number?)
KeyTwo = "ValueTwo"
}
-- You can access array's with number's: Array[3] would give: "Hello!"
So, we need to store the result.
local String = "Hello Everyone!"
local Result = string.split(String, " ")
for Index, Value in pairs(Result) do
print(Index, Value)
end
In this code, we are looping over the result of string.split which is an array. This script would give us: 1: Hello 2: Everyone!
It would give us this, because we told the function to give us the characters split by " ". Which is a string.
As you can see, it separates characters by the second argument you give it.
string.split(string, character to split by)
Usages: Admin Commands, More advanced string manipulating. And much more!
String.split is a function that splits a string using a given string you want into a table of each string that was split
For example:
local splitContents = string.split("hey, guys, where, who, when", ",")
Gives you a table where "hey", "guys", "where", "who", "when" is found (whitespaces included aka space you see that are not letters/commas)
You can iterate through this table:
for index, value in ipairs(splitContents) do
print(index, value)
end
This would print: 1 hey 2 guys 3 where 4 who 5 when
You could probably see why this is useful in admin commands for example.

TL;DR: It allows you to separate or group pieces of a String via a given delimiter (or regular expressions—patterns) into an array; this code splits by commas, therefore each word found after a comma will be met at a different index.

That explanation is short but probably gonna be confusing to the asker, for example, what is a "given delimiter"? But, that should be how I explained it, just separated words into different indexes including whitespace.
string.split(s string, string pattern) returns a table. It is used to split strings, as you know from the name. For example:
local splitter = string.split("hi,,there", ",")
will return the table:
{"hi", "", "there"}
After you split it, you can use a for loop to print out all the values in the table.
for i,v in pairs(splitter) do
print(v.." ["..i.."].")
end
I hope this helps!
