JSFLow is a security-enhanced JavaScript interpreter for fine-grained tracking of information flow written in TypeScript. JSFlow

• supports full non-strict ECMA-262 v.5 including the standard API,
• provides dynamic (runtime) tracking and verification of security labels,
• can be compiled to JavaScript, which enables flexibility in the deployment of JSFlow.

We invite you to try the console, or tackle the challenge.
