@OverHash What does that look like in typescript? And is there a resource I can look at for this?

This is luau things

local myTable { name = "Joe", age = 20 }

for i, v in pairs(myTable) do
    print(i, v)
end

local myTable { name = "Joe", age = 20 }

for i, v in pairs(myTable) do
    print(i, v)
end

will output

name Joe
age 20

name Joe
age 20

In TypeScript it just looks like the TS equivalent,

for (const [k, v] of pairs(myTable)) {
    print(k, v);
}

for (const [k, v] of pairs(myTable)) {
    print(k, v);
}

Wonderful! How did you come to know this? Are there any docs? (This is exactly what I needed thank you, you answered my question) No way are you saying this is a convention in vanilla TS? Am I crazy
