Data Structures and Algorithms with Javascript
Programming
Course Description
This course is designed to teach JavaScript developers essential data structures and algorithms needed to write efficient, scalable, and optimized code. Covering fundamental structures such as arrays, linked lists, trees, and graphs, alongside core algorithms like sorting, searching, and recursion, learners will gain both theoretical knowledge and practical coding skills applicable to interviews and real projects.
Duration: 3 Days
Format: Instructor-led, coding exercises, algorithmic problem solving, and real-world examples
