TypeScript AST Evaluator

ts-evaluator is an advanced interpreter for TypeScript that enables the evaluation of arbitrary AST (Abstract Syntax Tree) Nodes, specifically Expressions, ExpressionStatements, or Declarations, within a given TypeScript AST. Unlike tools such as `ts-node` that execute full TypeScript programs, this library focuses on partial evaluation based on a node's lexical environment. The current stable version is 2.0.0. Release cadence appears to be driven by significant TypeScript and JSDOM version updates, typically with several minor and patch releases in between. Its key differentiators include the ability to evaluate specific nodes, support for browser, Node.js, and pure ECMAScript environments, and configurable policy options for sandboxing and restricting operations like I/O or network access. This makes it a valuable tool for linters, language services, partial evaluators, and frameworks requiring deep AST introspection and computation.
