What

Brief

This is a standalone Min Heap data structure from the data-structure-typed collection. If you wish to access more data structures or advanced features, you can transition to directly installing the complete data-structure-typed package

How

install

npm

1npm i min-heap-typed --save

yarn

1yarn add min-heap-typed

snippet

TS

1    import {MinHeap} from 'data-structure-typed';
2    // /* or if you prefer */ import {MinHeap} from 'heap-typed';
3
4    const minNumHeap = new MinHeap<number>();
5    minNumHeap.add(1).add(6).add(2).add(0).add(5).add(9);
6    minNumHeap.has(1)        //  true
7    minNumHeap.has(2)        //  true
8    minNumHeap.poll()        //  0
9    minNumHeap.poll()        //  1
10    minNumHeap.peek()        //  2
11    minNumHeap.has(1);       // false
12    minNumHeap.has(2);       // true
13    const arrFromHeap = minNumHeap.toArray();
14    arrFromHeap.length       //  4
15    arrFromHeap[0]           //  2
16    arrFromHeap[1]           //  5
17    arrFromHeap[2]           //  9
18    arrFromHeap[3]           //  6
19    minNumHeap.sort()        //  [2, 5, 6, 9]

Software Engineering Design Standards

Principle	Description
Practicality	Follows ES6 and ESNext standards, offering unified and considerate optional parameters, and simplifies method names.
Extensibility	Adheres to OOP (Object-Oriented Programming) principles, allowing inheritance for all data structures.
Modularization	Includes data structure modularization and independent NPM packages.
Efficiency	All methods provide time and space complexity, comparable to native JS performance.
Maintainability	Follows open-source community development standards, complete documentation, continuous integration, and adheres to TDD (Test-Driven Development) patterns.
Testability	Automated and customized unit testing, performance testing, and integration testing.
Portability	Plans for porting to Java, Python, and C++, currently achieved to 80%.
Reusability	Fully decoupled, minimized side effects, and adheres to OOP.
Security	Carefully designed security for member variables and methods. Read-write separation. Data structure software does not need to consider other security aspects.
Scalability	Data structure software does not involve load issues.
