The thesis studies JavaScript variables as the foundation of control flow and state, emphasizing var, let, and const, scope, hoisting, temporal dead zone, and mutation control. Methods include comparative analysis, specification-oriented interpretation, and classification of common defects. Novelty is a coherent framework connecting execution contexts to practical guidelines for reliable, maintainable code.
