Help with if [variable] then statements?

Asked by

So when I see code such as this

local rebirth = game.Workspace.Events.Rebirth
 if rebirth then
    rebirth:FireServer()
end

Why is the variable inside the if/then statement. Everytime I've tried to learn what this means, I always think that it means if it sees the variable anywhere it runs. It always runs though, no matter what. Can someone explain this to me?

if will check to see if the provided condition is truthy - provided that rebirth is hooked to a valid object anywhere in your game, then it will be considered truthy. Your variable is essentially equal to true when called upon as a condition - purely because it exists. SummerEquinox 643 — 5y
