JavaScript for Data Science

Book Description

JavaScript is the native language of the Internet. Originally created to make web pages more dynamic, it is now used for software projects of all kinds, including scientific visualization and data services. However, most data scientists have little or no experience with JavaScript, and most introductions to the language are written for people who want to build shopping carts rather than share maps of coral reefs.

This book will introduce you to JavaScript’s power and idiosyncrasies and guide you through the key features of the language and its tools and libraries. The book places equal focus on client- and server-side programming, and shows readers how to create interactive web content, build and test data services, and visualize data in the browser. Topics include:

• The core features of modern JavaScript
• Creating templated web pages
• Making those pages interactive using React
• Data visualization using Vega-Lite
• Using Data-Forge to wrangle tabular data
• Building a data service with Express
• Unit testing with Mocha

Maya Gans is a freelance data scientist and front-end developer by way of quantitative biology. Toby Hodges is a bioinformatician turned community coordinator who works at the European Molecular Biology Laboratory. Greg Wilson co-founded Software Carpentry, and is now part of the education team at RStudio

书名：数据科学中的Java脚本

Java脚本是互联网的母语。它最初是为了让网页更具活力而创建的，现在它被用于各种软件项目，包括科学可视化和数据服务。然而，大多数数据科学家几乎没有或根本没有使用JavaScript的经验，而且大多数对该语言的介绍都是为那些想要构建购物车而不是分享珊瑚礁地图的人写的。

本书将向您介绍JavaScript的强大功能和特性，并指导您了解该语言的主要功能及其工具和库。该书对客户端和服务器端编程给予了同等的关注，并向读者展示了如何创建交互式Web内容、构建和测试数据服务以及在浏览器中可视化数据。主题包括：

• 现代Java脚本的核心功能
• Creating templated web pages
• 使用Reaction使这些页面具有互动性
• Data visualization using Vega-Lite
• 利用Data-Forge对表格数据进行篡改
• 使用Express构建数据服务
• Unit testing with Mocha
