ExpressionParser

Secure expression parser that uses AST-based evaluation instead of eval() or new Function()

This parser provides:

• Security: No arbitrary code execution, only whitelisted operations
• Performance: AST caching for repeated expressions
• Better errors: Clear error messages with position information
• Type safety: Strongly typed AST and evaluation

Static Methods

static clearCache(): void;

static evaluate(expression: string, scope: EvaluationScope): unknown;

static getCacheStats(): { size: number; maxSize: number; };

static parse(expression: string): ASTNode;
