Is there a chart somewhere showing feature parity with typescript?

There are really three different “dimensions” of feature parity: 1. Core programming model - you can compare which features are noted as not yet implemented for each language here: https://www.pulumi.com/docs/intro/concepts/programming-model/ 2. Libraries and providers - you can compare what libraries are available for each language here: https://www.pulumi.com/docs/reference/pkg/ 3. New experimental features outside of core Pulumi (like the new Query experiment, and the new Policy as Code feature) - these are often built initially in one language for early feedback and later expanded out to others before GA.
