While JavaScript *allows* global properties on Strings to be added, it's not necessarily a good idea, as those are global (and could interfere with other things). To reduce the risk of future problems, use a created function instead, to avoid conflicts. This also adds a myAssert and improves internal comments about indexing as related changes.
