1. Background Introduction React is a JavaScript library for building user interfaces. It was originally open sourced by Facebook in 2013. Its powerful functions, excellent performance, simplicity and ease of use make it one of the most popular front-end frameworks currently. In recent years, the React community has also undergone some changes, including the rise […]

StopWatch – elegant program timer
? StopWatch – elegant program timer Program timer During our development process, in order to better monitor the operation of the system, interface, and business, we generally monitor the running time of the program. Initially, we used System.currentTimeMillis() to obtain the start and end times and then subtracted them. Thereby obtaining the program running time, […]
[Data structure: Heap] Large root heap, small root heap, heap upward adjustment algorithm, downward adjustment algorithm and heap function implementation!
Foreword This series of articles [Data Structure] will use C/C++ for design and implementation by default! For implementation methods in other languages, please refer to the analysis and design ideas to implement it yourself! Note[1]: The article is a study summary and does not have the corresponding sequence compared to the textbook! (You can check […]

Algorithm idea for upward adjustment of heap Algorithm idea for downward adjustment of heap Implementation of heap (C language)
Introduction to heap The heap uses an array to store a complete binary tree. Generally, a sequence table is used to implement the heap data structure. Properties of the heap: The value of a node in the heap is always no greater than (large heap) or no less than (small heap) the value of its […]

Put on the coat of App and keep the soul of the Web – PWA revisits the past
As early as 2015, designer Francis Berryman and Google Chrome engineer Alex Russell proposed the concept of “PWA (Progressive Web Application)” to combine the strengths of the web with the strengths of applications. Its core goal is Improve the performance of Web App and improve the smooth experience of Web App to be comparable to […]
Handwritten database wheel project MYDB Part 5 | DataManager (DM) Data page indexing and upward management DataItem
This chapter introduces a simple page index and implements the DM layer’s abstraction of the upper layer: DataItem. 1. Page index Page index, which caches the free space of each page. It is used to quickly find a page with suitable space when the upper module performs an insertion operation without checking the information of […]
