Nicholas Zakas

The document discusses JavaScript variable performance, particularly focusing on execution contexts, scope chains, and identifier resolution. It emphasizes that local variable resolution is faster compared to those deeper in the scope chain and suggests recommendations to optimize variable access. The author, Nicholas C. Zakas, highlights the importance of storing local references and avoiding the 'with' statement to improve performance.
