What specifically do you think would be better? Lua shares many of JS's quirks (like the relationship between arrays and non-array objects, the behavior of undefined for non-existent object properties, metatables are somewhat similar to JS prototypes, etc.) and adds a bunch more (lack of continue statement, 1-indexing, cannot have nil values in tables).
I can see people liking or disliking Lua and JS both, depending on taste, but it's hard to see someone liking one and disliking the other.
