What is the easiest way to index a table?

I believe to do it you use

table[index]

but I was wondering if there are other ways besides looping through the table?

You loop through a table if you don't know all indices.

For table indexing you generally use table[index]... this is also the "easiest" way.

Honestly, my favorite indexing is table.index, but that only works with strings that doesn't start with numbers and has no spaces. Only when I have varying index I use the square brackets.
