Using SVG (Scalable Vector Graphics) in React Native requires a bit of additional setup because React Native doesn’t support SVG out of the box. You can use SVGs in your React Native app by using a library like react-native-svg. This library provides SVG support for React Native and allows you to use SVG files or SVG code directly in your components. InstallationNpm: 1npm install react-native-svg Yarn: 1yarn add react-native-svg Linking (for React Native versions < 0.60): 1react-native link ...

English？Click here 写在最前作为 Leetcode 刷题系列的前言，我想给大伙儿和我自己说明一下这个系列的目的和参考。大家如果点进这篇文章就说明大家其实都想通过 Leetcode 来提升自己的码字实力，我与大家一样也渴望通过刷题通过后面的面试，而记录在博客不单单是为了记录这过程中我的所做所想，同样还为了对未来的自己提供一个可以快速复习的资源。当然如果这些文章能给你们也带来帮助那更好，这也证明我的文笔没有想的那么烂哈哈哈哈😂 题组来自哪？很多人跟我一样在第一次接触 Leetcode 时对于该去刷哪道题完全没有头绪，在这里就要非常感谢这些将所有的题目进行过滤并进行排序组合的大佬们给后辈们铺好了路！资源有很多，但目前来说我将以 “代码随想录” 提供的刷题攻略进行练习，在这里再次感谢他们无私的奉献！！！ 代码规范在刷题时，代码的规范性同样需要注意，这也是一个巩固自己代码规范的机会。很多人不屑于了解代码规范，将重心放在功能的实现上，这在未来大公司的小组里是非常致命的！不规范的代码会对后期的维护十分困难，也是公司招人的一个标准。 变量命名主流有三种： 小驼峰、大驼峰命名法 ...

Hopefully, these post would be a great review of what I learned, and might give you some advice on how to solve these questions. Where they from? (Link at References)It is better to now what/which question should you take before we start doing them, or you will not know where to start, where to go next level. Thus, I found a GitHub repository about the leetcode que ...

WebSocket ServerTeach you how to write a simple server:) The Problem In CSE115 you used HTTP request / responses to build web apps If you wanted more data from the server after the page loads, you used AJAX Server hosts JSON data at certain end points Client makes an AJAX call to retrieve the most current data But the server has to wait for a request before sending a response What if the server wants to send time-sensitive data without waiting for a request?
