Is a difference / impact to code if i set "variable = false" in an event without to check it if is true ?

Like:

function OnClick() { variable = true; or variable = object }
function OnMouseMove() { variable = false; or variable = null }

But is set every time false or null. Need to check first ?

Sure, it'll now be defined and set to `false` instead of being an undefined variable. – ceejayoz Feb 27 '19 at 16:15
Thanks for a small think but important. – Feb 27 '19 at 16:40
