Oftentimes the same function will be used for initialising an observer and updating it in response to a change:
local theValue = Value(5)
local function updateFoo()
foo.Color = theValue:get()
end
updateFoo()
Observer(theValue):onChange(updateFoo)Sometimes this may not be expressed explicitly:
local theValue = Value(5)
foo.Color = theValue:get()
Observer(theValue):onChange(function()
foo.Color = theValue:get()
end)To reduce code duplication and the potential for errors, we could introduce a shorthand which immediately invokes the callback function in a spawned thread:
local theValue = Value(5)
Observer(theValue):onBind(function()
foo.Color = theValue:get()
end)
