The motivation for writing this book was the lack of resources available about data
structures and algorithms written in JavaScript. This was strange to me because

JavaScript; it is the only language that can be used to write the entire stack, including the
front-end, mobile (native and hybrid) platforms, and back-end. It is crucial for JavaScript
developers to understand how data structures work and how to design algorithms to

means copying the objects and changing their properties.

covers implementations and algorithms for fundamental data structures such as linked
