提高编码效率的15个最新JavaScript包和工具
一个JavaScript库是一个预先写好的JavaScript库，可以更轻松地开发基于JavaScript的应用程序，尤其是对于AJAX和其他以Web为中心的技术。
1. Recline.js
Recline.js is a powerful library for building data apps in pure HTML and JavaScript. It provides components and structure to data-heavy apps by providing models and views.
2. Keypress
Keypress is a JavaScript library for capturing keyboard inputs and manipulating them flexibly. It can be used for simple cases (like if “x” is pressed, trigger a function) and more advanced scenarios like creating combos of any type. The library has callbacks for keyup + keydown events, an option exists for capturing the input only once and much more.
3. Pace.js
PACE is a JavaScript library for adding good-looking loading bars to any website with ease. There are multiple loading effects: 油Tube-like, corner indicator, page fill and more. It requires very less effort; simply insert the JavaScript file with the selected theme and PACE works automatically for page load and ajax requests. The library doesn’t require any JS frameworks and can, optionally, be tweaked manually.
4. BackgroundCheck
BackgroundCheck is a small JavaScript library for preventing such issues byauto-changing the style of the element to a darker or lighter one. Once an element overlaps an image, it adds .background–dark or.background–light classes to it. And, creating the related styles for each class would be enough. It is possible to limit the functionality to only selected images, define the dark/light threshold and more.
5. TogetherJs
TogetherJS is a free, open source Javascript library by Mozilla that adds collaboration features and tools to your website. By adding TogetherJS to your site, your users can help each other out on a website in real time. TogetherJS is implemented in Javascript; no software or plugins to install, and it’s friendly with existing web pages, while still letting developers customize the experience. TogetherJS is built and hosted by Mozilla, so you know it’s safe to use.
6. Vex
Vex is a JavaScript library for creating very good looking modal boxes. The library is standalone + lightweight (2kb minifed + gzipped) and comes with an easy-to-use API. It has smooth animations, a built-in CSS spinner and replacesalert, confirm, and prompt out of the box. Vex also works well on mobile browsers and its design can be customized quickly.

8. David

9. QuestionMark.js
QuestionMark.js is a small script that uses AJAX to display a modal window of shortcut key definitions for your site or app. It’s easy to customize for your own shortcut key needs.
10. Harp
Harp runs directly with the built-in web server, or exported to HTML, CSS, and JS, and automatically delivers files the browser needs with no pre-compile step. It works with Markdown, Jade, EJS, CoffeeScript, Stylus, and LESS, and lets you publish to Amazon S3, GitHub, and more.

15. LiveScript
