I tried to make the code to 140b. I couldn't so I figured out to give it to do it

u/ximavus

t<1?s='\n':b='Backspace' e='Enter' x.reset() onkeydown=k=>{o=k.key;l=o.length<2|o==b|o==e?k.key.replace(e,'\n'):'';l!=b?s+=l:s=s.slice(0,-1)} x.font='2cm a' h=s.split('\n') for(i=h.length;i--;)x.fillText(h[i],0,60*i)
u/ximavus

the code I posted is like a text editor. Maybe someone of you watching this can make it run! Congratulations to the one who does it (if possible)
