What are the data types in Lua?

Lua has several basic data types, including:

  1. Nil: Represents the absence of a value. It is the only value that is not equal to itself.

    local x = nil
    
  2. Boolean: Represents true or false values.

    local isTrue = true
    local isFalse = false
    
  3. Number: Represents both integers and floating-point numbers. Lua does not differentiate between the two.

    local integerNum = 10
    local floatNum = 10.5
    
  4. String: Represents a sequence of characters. Strings can be enclosed in double or single quotes.

    local greeting = "Hello, World!"
    local farewell = 'Goodbye, World!'
    
  5. Table: The only composite data type in Lua, used to represent arrays, records, lists, queues, etc.

    local fruits = {"apple", "banana", "cherry"} -- Array-like table
    local person = {name = "John", age = 30} -- Record-like table
    
  6. Function: Represents a block of code that can be executed.

    local function add(a, b)
        return a + b
    end
    
  7. Thread: Represents an independent line of execution. This is used for coroutines.

    local co = coroutine.create(function()
        print("Hello from coroutine!")
    end)
    

For handling large-scale data and complex computations in Lua, especially in cloud environments, services like Tencent Cloud's Cloud Functions can be utilized to manage and execute Lua scripts efficiently.
