Who am I

I am a seasoned software development engineer with 15 years of professional experience. Following my graduation from university, I have contributed my expertise to various software companies across diverse industries, including some prominent ones.

Of course, I have my flaws, I have a nerd-like attitude towards technology and could be described as a perfectionist. For instance, being excessively serious and having a penchant for studying the essence of things, I sometimes come across as a stern boss, which can be intimidating to my wife and daughter.

Fortunately, my outlook on life is broad-minded. when it comes to life and family, the keywords are love, loyalty, and appreciation of beauty. I also enjoy studying cultural differences in various regions. Deep down, I actually have a bit of an artistic flair. LOL, just writing this makes me want to laugh!

Current Situation

My recent move to Malaysia was motivated by the desire to provide my daughter with a formal education(Yes, you read it correctly, it is the word 'formal', because the education system in some countries is not normal), and it comes alongside holding a 10-year residency visa(MM2H). However, this visa restricts my employment opportunities within Malaysian companies. Fueled by my passion for programming and recognizing the absence of a standardized data structures library in JavaScript/TypeScript, I embarked on the journey of implementing my own set of data structures - data-structure-typed within the open-source community.

data-structure-typed Project Overview

Ultimate Goal

  • To seamlessly integrate into the standard library of JS/TS.

Pain Points Addressed

Enhanced the Performance of Simulated Data Structures in JS/TS

  • Queue: While many resort to using Array to simulate Queue and Deque, the time complexity of Array.shift is O(n). We have tackled this by implementing a Queue and Deque with O(1) time complexity.

  • HashMap: The built-in Map in JS is actually a LinkedHashMap, as it maintains the insertion order of elements, resulting in performance inferiority compared to a pure HashMap. We have implemented a pure HashMap.

Introducing Missing Native Data Structures in JS/TS

  • Heap / Priority Queue: Algorithms with O(log n) time complexity have been pivotal in improving efficiency since the dawn of computers. A Heap supports insertion, deletion, and search with O(log n) time complexity, coupled with the ability to obtain the minimum / maximum value in O(1) time.

  • Red Black Tree: Developers well-versed in databases, file systems, Linux virtual memory management, and network routing tables often have a nuanced understanding of Red-Black Trees. It stands out as the least operation-intensive among all balanced binary search trees, offering optimal performance balance in CRUD operations.

Advantages

Performance:

  • The performance of some ours data structures has surpassed JS's built-in data structures, such as Queue, Deque and HashMap, while most are comparable to or even surpass those in other languages. Some are still undergoing refinement, notably the Graph and AVL Tree.

Uniformity

    1. Concise and industry-standard naming：Implementation or constraint of forEach, filter, map, every, some, reduce, find, has, hasValue, get, print, isEmpty, clear, clone methods in the base class.
    1. Adhere to the ES6 specification: Use of generators to uniformly implement [Symbol.iterator], entries, keys, values. Delaying iterator execution prevents performance loss and provides control during traversal. All deletion methods uniformly use the widely adopted delete in ES6, while addition methods uniformly use add. Compatibility with some specifications in Java.
    1. Constructors：The first parameter for all constructors is data, and the second parameter is configuration, maintaining uniformity. The first parameter accepts any iterable type for seamless conversion between data structures.
    1. Return types：for example, the add method consistently returns a boolean.

We would like to provide a more detailed description of this project, but space is limited here. For specific technical details, please refer to the README.md, SPECIFICATION.md, or API Docs.
