DSA.js is a collection of data structures and algorithms implemented in JavaScript, available as an NPM package and accompanied by an eBook. It serves as both a reference manual for developers and study material for coding interviews.

Use cases

• prepare for coding interviews with data structures and algorithms
• learn how to implement linked lists, stacks, and queues in JavaScript
• understand Big O time complexity with worked examples
• refresh knowledge of trees, graphs, and heaps before an interview
• use ready-made data structure implementations in a JavaScript project
• study algorithm techniques to solve problems more efficiently

When to choose

• you are a JavaScript developer preparing for technical interviews
• you want readable reference implementations of classic data structures
• you prefer learning algorithms with explanations paired with code
• you need an installable NPM package of common data structures

When to avoid

• you need production-grade, highly optimized data structure libraries
• you work in a language other than JavaScript
• you want interactive visualizations or video-based courses
• you need advanced or niche algorithms beyond the fundamentals
