small correction - use `:size` in the three lines near the bottom (rather than `size`)

I tried it on https://www.calormen.com/jslogo/ and saw this small typo

cheers!

p.s. same as you, I was introduced to Logo around the age of 8 and I remember writing programs on paper when I was home, stepping through them line by line... it was inevitable I'd gravitate towards programming, ha :-)
