What do [] brackets do and the other ones if my understanding is wrong?

I have seen all kinds of brackets these : {} I think are for tables these () I think are for parameters . BUT THESE [] I cannot understand. I don’t get what [] bracket do.

I'm not sure on the proper reason as to why but I have seen them used, and used them in tables for callable number names for tables, alongside getting to the child of an instance if that instance has a name with a space. I.E workspace["Roblox Headquaters"] Protogen_Dev 268 — 2y

You can use it for either finding a child or getting a poperty of an instance. SuperPuiu 497 — 2y

A lot of times it's used to get certain stuff out of tables or dictionary's, but it can also be used to find a child inside of Workspace or another place, It can find children with spaces

Dictionary example: (Tables and Dictionary's are almost the same}

01-- Make the dictionary using the [] brackets to name them!
02local fruitDictionary = {
03    ["Bananas"] = "Not my favorite";
04    ["Apples"] = "Pretty good";
05    ["Eggplants"] = "Sus";
06}
07 
08-- Print the Eggplants
09print(fruitDictionary ["Eggplants"])
10-- When you run the script it should say sus!

Children Example

`1`	`workspace["My Part that has a space"].BrickColor` `=` `BrickColor.new("Bright green")`

Hope this answered your question!

Square brackets are used to reference items in a table. For example:

1local table = {12, 41, 62}
2 
3print(table[2])  --prints 41
4 
5table[2] = 123
6 
7print(table[2])  --prints 123
8 
9print(table[1])  --prints 12

They can also be used to reference table keys that are strings:

1local table = {
2    ["oranges"] = 152,
3    ["apples"] = 127,
4    ["potatoes"] = 4
5}
6 
7print(table["apples"])  --prints 127

Square brackets can be used to find things you may not be able to without using them. another use is for picking a certain item in a table

1part = workspace.my part -- This will not work
2part = workspace["my part"] -- this will work
3 
4mytable = {one, two, three}
5 
6mytable[2] = "seven"

I hope this makes sense
