Lua Quick Start Guide

Finding a type

There is one very important function built into Lua, type. This function will return the type of a variable as a string. Let's take a look at this function in action:

var1 = truevar2 = 3.145var3 = nilvar4 = type(var1)var5 = type(type(var2))print (type(var1)) -- booleanprint (type(var2)) -- numberprint (type(var3)) -- nilprint (var4) -- booleanprint (var5) -- string

Because the type function returns a string, the result can be assigned to a variable, like so:

var4 = type(var1)

Or, the result can be passed directly to a function such as print, like so:

print (type(var1))

The type of the type of something type(type(var2)), as represented by var5, will always be a string. This is because, as stated before, type returns a string. ...
