#mouse position using innerWidth

u/ElisionFR

Where does innerWidth come from and why does it stop working when I put it outside the event ?
u/ElisionFR

Never mind, if I do that c.width= clears the canvas
u/tomxor

innerWidth is just a global (on window) which in the context of the dweet is the iframe which is conveniently the same size as the canvas... It does work outside of the event handler but you have to remember to move the draw function out as well since it will only draw when mouse is being moved.
u/pavel

onmousemove=e=>x.fillText('🐁',e.x,e.y,c.width=innerWidth,x.font='3em"')
