where I could study data structure in javascript

I have a strong desire to build a solid foundation in data structures and algorithm complexity, starting from the fundamentals and gradually progressing to more advanced topics. However, I’ve encountered challenges in finding comprehensive resources to facilitate this learning journey. While I have been diligently following the FreeCodeCamp course, I’m uncertain whether it alone is sufficient to fulfill my ambitions.

In light of this, I’m seeking advice and recommendations on where to further enhance my knowledge and practical skills in data structures and algorithm analysis. The goal is to become a proficient programmer, capable of solving complex problems and optimizing code for efficiency
