{} is not equal to {}

local canUpgrade = false
print(parentUpgrades)
if parentUpgrades == {} then
   canUpgrade = true
end
print(canUpgrade)

line 25 prints {} (as it should)
line 29 prints false (should not)
for some reason, the if statement says parentUpgrades is not equal to {} even though the print statement clearly said it was. i tried nil and even an empty table equal to {} instead of {} in the if statement, nothing changed

By writing {}, you're creating a table literal

Each table occupies a different array of contiguous bytes in memory, each with a separate initial memory address

You're not checking if a table is empty, you're checking if a table is equal to another

This is never true, due the above reason

To check if an array is empty, use the length operator to get the number of elements within the array, and compare that number to 0:

if #array == 0 then

To check if a dictionary is empty, query the first key-value pair via next, and compare it to nil:

if next(dictionary) == nil then

The latter method works for both dictionaries and arrays

uhn

basically like doing print(Instance.new("Part") == Instance.new("Part"))

it will always be false unless they refer to the exact part
