课程名称：学习JavaScript与NodeJS（并构建加密货币机器人） 课程概述：该课程现为**发售特别价**，定价为49.99澳元，将于2022年1月31日结束，之后价格将上涨至79.99澳元（自2022年2月1日起）。课程内容短小精悍，完全动手实践，将教会你如何使用JavaScript和NodeJS编程，同时构建一个可能帮助你获利的酷炫加密项目。非常适合任何初学者或对加密货币感兴趣的人。 本课程与其他在线课程的不同之处在于，强调帮助你成为一个独立的开发者。在这里，你将学习如何进行有效的研究以及如何整合第三方服务，以便独立开发自己的项目。课程独特之处在于结合了加密货币和编程的焦点，提升与这一热门新兴技术相关的编码技能。你将实际构建一个有用的项目，而不仅仅是创建一些基础的小游戏或计算器。同时，本课程对JavaScript和NodeJS进行双重介绍（很多课程只覆盖其中之一），并通过简单清晰的动画解释概念，不再是单调的要点讲解。课程时间投资要求低，最大90分钟，能够帮助你决定是否进一步投资其他课程。 课程结构分为三个部分： 第一部分：学习JavaScript的理由、环境搭建（控制台和代码编辑器）、浏览器中的控制台使用、基础概念（变量、注释和函数）。 第二部分：网页抓取（提取网站数据的方法）、网站结构（HTML、CSS和文档对象模型DOM）、从CoinMarketCap网站抓取加密货币价格、调试和研究技巧、基础概念（条件逻辑、异步编程、对象、数组和循环）。最终将编写出一个浏览器中运行的程序，自动检索加密货币价格，无需手动搜索。 第三部分：对第二部分程序进行升级和清理、NodeJS安装及使用、基础概念（依赖库和API）、设置并连接Twilio API（使用免费试用账户）以自动发送短信通知。最终将得到一个NodeJS程序，能自动检索加密货币价格并在价格触及特定阈值时，通过短信通知你。 下一步：完成课程后，不要止步不前！还有许多方式可以进一步升级机器人，例如：增加更多加密货币及其价格、增加短信内容、让机器人每x分钟运行、在无服务器托管服务（如AWS Lambda）上托管程序，使其持续运行、为机器人创建界面、添加更复杂的逻辑（如将币价与趋势等其他指标进行比较）等。
**LAUNCH SPECIAL** This course is priced at $49.99 AUD until 31 January 2022.The price will then go up to $79.99 AUD on 1 February 2022.***Short, concise and fully hands-on, this course will teach you how to code in both JavaScript and NodeJS, while building a cool crypto-based project that may potentially help you to make money.Highly suitable for any absolute beginners or cryptocurrency enthusiasts.How is this course different from the other online courses?Strong focus on helping you become a self-sufficient developer. In this course, you won't just learn to code for the sake of coding. You will learn effective research tips and how to integrate third party services so that you can independently learn and build your own projects.Unique cryptocurrency x programming focus - build coding skills that are relevant to a hot emerging technology.Actually build a useful project (not just a basic flash game, calculator or local webpage) that can potentially add value to your life.Dual overview of JavaScript and NodeJS (many courses only just cover one of them).Simple and clean animations to explain concepts. Not just a plain bulletpoint lecture.Low time investment. Max 90 minutes. This course can help you consider whether to invest further in other courses.Course structureThis course has three parts:Part OneWhy learn JavaScript?How to get things set up (consoles and code editors)How to use the console in your browserFundamentals: variables, comments and functionsPart TwoWeb scraping (i.e. a technique to extract data from a website so that you can use the website data in your programs)Website structure (HTML, CSS and Document Object Model (DOM))Scraping crypto prices from the CoinMarketCap websiteDebugging and research techniquesFundamentals: conditional logic (if/else), asynchronous programming, objects, arrays and loops.End outcome: Your first program (runs in the browser) that can automatically retrieve cryptocurrency prices without you have to manually search them up!Part ThreeUpgrading and cleaning up the program from Part TwoNodeJS (installation and how to use it)Fundamentals: dependencies/libraries and APIsSetting up and connecting to Twilio API (with free trial account) to automatically send text messages to your phoneEnd outcome: A NodeJS program that can automatically retrieve cryptocurrency prices and notify you via SMS text whenever one of the prices hits a certain threshold!What's the next step?Even after you have completed this course, don't just stop here! There are many ways to further upgrade the bot. Ideas could include: Adding more crypto coins and prices to the botAdd more content to the text messageGet the bot to run every x minutesHost the program on a serverless hosting provider (e.g. AWS Lambda) so that it runs constantlyCreate an interface for the botAdd more complex logic (i.e. compare coin prices against trends, other metrics, etc)
