Beyond the economic arguments, there’s a lot in JS that actually makes it a lot easier: almost all of the operators can only return a subset of the types and cannot be overridden (e.g., the binary + operator in JS can only return a string or a number primitive), the existence of like string and number primitives dramatically reduce the amount of dynamic behaviour they can have, only proxy objects can exhibit the same amount of dynamism as arbitrary Python ones (and thus only they pay the performance cost)… |
