Boolean Not Equal To in Lua programming

Question

How to write if statement in Lua with not equal symbol for boolean variable.

//In Java, 

boolean a;
a = false;
if(!a){
    //do something
}

-- In Lua I am trying to replicate the same code 

local a
a = false
if(~a) then
    -- do something
end

But I am getting error. How to write this in Lua ?

Answer 1

Lua uses mostly keywords. Use not a instead of ~a.
