[Question] Quick Array Question

Does saying t = {}
the same as saying t = {nil,nil,nil}

In that example, it is the same thing. But if you were to do t = {nil, nil, nil, 1, 2, 3} then the 1 would be the 4. index(obviously :D/>/>) instead of being the first when done like t = {1, 2, 3}

Tables are different from arrays in other languages, they are less strict and allow for multiple data types, including tables and functions.

Tables are also sets of key-value pairs, meaning that if you make a statement like

 t[5]="hello" 

you are setting key 5 of the table to the value of "hello". Any Key that isn't set is automatically nil, so nil is technically the default value of every key.

Therefore, calling

 t={nil,nil,nil}

is essentially the same as calling:

t={} t[1]=nil t[2]=nil t[3]=nil

but since t={} makes all the values in the table nil by default, they are again, essentially the same thing, so

t={nil,nil,nil}

is redundant, as well as

 t={} t[1]=nil

etc

However, if you were to call

t={nil,nil,nil,"hello"}

, it would be the same as calling

t={} t[1]=nil t[2]=nil t[3]=nil t[4]="hello"

thus making it different, however calling

t={} t[4]="hello"

would be a much better method as it is shorter and achieves the same result.

And that is basic table assignment in a (wal)nutshell.
