Type correspondence between JS and MistQL

Separate from the specification of the language, the JS implementation maps from JS types to MistQL types in a specific manner, as documented by the table below. As the following is NOT part of the language, rather the library, the correspondence may change with further releases of the mistql package, following semver.

If this correspondence doesn't work for you for some reason, please open an issue and describe the situation carefully. This correspondence is easier to change than the language itself.
