Python Development Techdegree Student 824 PointsGood work.
In the for statement, you are using
i = 0
and what that does, with nolet
,const
or even the lesser usedvar
, is seti = 0
against the global object.In the browser, that is
window
in the browser, andglobal
in nodejs.This would mean that if something else in the
global
namespace had set the value fori
already, your loop has just overwritten it. You can scope the variable to just thefor
loop by changing it tolet i = 0
.
