JS is a loose type language by definition. Biggest problem for JS, from the beginning was people start writing without completely understanding it. Even myself seeing my initial JS code feel embarrassed. Noone understand what is or handle loose typing, prototype, closures, functional concepts like currying before coding. I took almost an year to understand same. Although that time there are hardly my resources like now. But I still see, people directly jumping into JS.
