FAQ

Does ESInfer support all javascript features?

Our goal is to support all ES6+ features incrementally. Of course,
use frequency is the main factor in deciding which comes first.
Currently, it supports nearly all(except a few built-in methods
unimplemented, which will do) ES5 features and a select set of ES6+
features, such as Array/Object destructing. If you have any concerns
regarding the feature set, please leave a message at the discussion
repo on Github.

Is ESInfer a superset of javascript or vice versa?

ESInfer is not a superset of javascript. It analyzes statically
without any add-ons to the language or your code. That is to say that
you get all benefits from ESInfer at zero cost. On the other hand, it
is not a subset of javascript either. It will warn of the potential
problem code, such as calling a non-existing method on an object.
Stimunously allows, for example, the modification of prototypes
dynamically to maximize your development experiences.
