How Can I Index Numbers In A Table?

I'm storing numbers in a table like this:

local table = {231, 5353, 2867}

I'd like to know if there's a possible way to index those values like this:

table[5353]

I thought about changing the table format to {[231] = true} however that method won't work with JSONEncode. If anyone knows a possible solution, please let me know.

Also, i'm trying to avoid having to loop through the table just to make things easier.

In the Lua language, [] is not used to index table values. The second script bar would represent the 5,353rd value in the "table" table.
