Senior JavaScript Developer

This test is designed for senior-level JavaScript developers. It consists of 7 coding challenges and 3 theoretical multiple-choice questions. The coding challenges focus on advanced algorithmic problem solving and efficient data manipulation using JavaScript, with deterministic input/output scenarios and multiple edge-case test scenarios to ensure robust solutions. The theoretical questions assess in-depth understanding of key JavaScript concepts including asynchronous programming, data types, and contextual behaviors of the 'this' keyword.
