Ungayiphindisela njani phezu kwezitshixo kunye namaxabiso ento kwiCofiScript?

Ndinento (edibanisa uluhlu) ukuze ithiwe - eyaziwa ngokuba yinto yeJavaScript ecacileyo):

obj = {}
obj["Foo"] = "Bar"
obj["bar"] = "Foo"

Ndifuna ukuyilungisa ngaphezulu obj ndisebenzisa iKofiScript ngolu hlobo lulandelayo:

# CS
for elem in obj

bu ikhowudi ye-CS apha ngasentla iqulunqa iJS:

// JS
for (i = 0, len = obj.length; i < len; i++)

engafanelekanga kule meko.

Indlela yeJavaScript izakuba ye (var key in obj) kodwa ngoku ndiyazibuza: ndingayenza njani le nto kwiCofiScript?
