Comparing Tables

Help and Feedback Creations Feedback
#1

Hi, I’ve Created A Function That I Think Is Useful

                               **CODE**
function CompareTable(Value,Table)
	if typeof(Table) ~= "table" then
		error("table expected, got " .. typeof(Table))
	end
	for i,v in pairs(Table) do
		if v == Value then
			return true
		end
	end
	return false
end

Easy But Efficient And Useful

Usecases

  • Do not use or to for not lengthen your code

Module

I think that it would be better if instead of returning true you return i.

#3

is a boolean function

I can give you the code

function CompareTabletoIndex(Value,Table)
	if typeof(Table) ~= "table" then
		error("table expected, got " .. typeof(Table))
	end
	for i,v in pairs(Table) do
		if v == Value then
			return i
		end
	end
	return false
end
#4 
function compare(v, t)
    assert(type(t) == 'table', 'no')
	for _, _v in next, t do
		if _v == v then
			return true
		end
	end
	return false
end

I think it would be good to give a type to the Table parameter, and enable strict typing, that way you don’t have to perform a check to make sure the value passed is a table type.

I don’t know the assert ​function

#7

basically an error if statement in one line

assert(statement, this code will run if the statement is false)

#8 
if typeof(Table) ~= "table" then
    error("table expected, got " .. typeof(Table))
end

does the same thing as

assert(typeof(Table) == "table", "table expected, got " .. typeof(Table))
#9

is it like this disassembled?

function assert(statement,error)

if not statement then

error(error)

end

end)

This linear search algorithm is equivalent to table.find which is defined in C++ and thus will run faster than any Lua implementation.
