Could you build this?
No Building an in-JS AST interpreter for JavaScript, TypeScript, and JSX that executes safely under strict Content Security Policies requires deep language semantics and compiler engineering.
What it would actually take: The engine needs an AST parser (like Babel or SWC bindings) and a bespoke interpreter/evaluator loop written in JavaScript that manually implements ECMAScript specifications (scopes, prototypes, async/await, closures, and JSX runtime factories) without using eval() or new Function(). The system must handle deep edge cases like prototype poisoning, circular references, and execution bounds. It requires specialized expertise in programming language implementation and runtime security.
