A data structure refers to a collection of data elements that have one or more specific relationships with each other. Often, carefully selected data structures can lead to higher operating or storage efficiency. Data structures are often related to efficient retrieval algorithms and indexing techniques.

Immutable Data Structures in JavaScript for Predictable State
21 Aug 2025
Using immutable data structures can improve the state predictability of JavaScript applications because they prevent unexpected side effects, simplify debugging and support efficient change detection; in React or Redux, errors should be captured by using non-mutated methods (such as map, filter, concat, extension operator), Object.freeze(), or deep immutability should be achieved through the use of immer and other libraries, while following best practices such as always returning new references, reference comparisons with ===, and normalizing state structures, to ultimately achieve maintainable and predictable state management.
attrs and cattrs: Tutorial for elegantly handling nested data structures
05 Aug 2025
This tutorial explains in detail how to use Python's attrs and cattrs libraries to efficiently handle nested data structures, especially converting complex data containing dictionary lists into attrs-defined lists of class instances. The article will explain the limitations of the attrs built-in converter and demonstrate how cattrs can automatically and gracefully map from raw dictionary data to complex attrs objects through its powerful structured capabilities, simplifying code and improving maintainability.
