How do I get better at using tables?

A table is a list. This list can contain absolutely anything. To create it, we just use a regular variable name, followed by curly brackets.

local t = {}

Now we just put anything we want inside of those brackets - separated by commas.

local t = {"Hello, world!", workspace.Part, true}

Notice how we can put all types of values in the table.

We can add values, remove values, etc. with table manipulation functions.

To access a value from a table, we need to use something called a key. The key is what you use to get the value. For simple lists, the keys are numbers:

local t = {"Hello, world!", --Key: 1
        workspace.Part, --Key: 2
        true}  --Key: 3

To use a key, we put brackets after the table's name, followed by the key. This gives us the value corresponding to the given key.

print( t[1] )
--> Hello, world!

There's also ways where we can edit what key corresponds with what value. This video covers it pretty well.
