A practical functional library for JavaScript programmers.

There are already several excellent libraries with a functional flavor. Typically, they are meant to be general-purpose toolkits, suitable for working in multiple paradigms. Ramda has a more focused goal. We wanted a library designed specifically for a functional programming style, one that makes it easy to create functional pipelines, one that never mutates user data.

The primary distinguishing features of Ramda are:

• Ramda emphasizes a purer functional style. Immutability and side-effect free functions are at the heart of its design philosophy. This can help you get the job done with simple elegant code.

• Ramda functions are automatically curried. This allows you to easily build up new functions from old ones simply by not supplying the final parameters.

• The parameters to Ramda functions are arranged to make it convenient for currying. The data to be operated on is…

CesiumJS is a JavaScript library for creating 3D globes and 2D maps in a web browser without a plugin. It uses WebGL for hardware-accelerated graphics, and is cross-platform, cross-browser, and tuned for dynamic-data visualization.

Built on open formats, CesiumJS is designed for robust interoperability and scaling for massive datasets.

Visit the Downloads page to download a pre-built copy of CesiumJS.

If you’re building your application using a module bundler such as Webpack, Parcel, or Rollup, you can install CesiumJS via the cesium npm package:

npm install cesium --save

Then, import CesiumJS in your app code. Import individual modules to benefit from tree shaking optimizations through most build tools:

import { Viewer } from "cesium";
import "cesium/Build/Cesium/Widgets/widgets.css";

const viewer = new Viewer("cesiumContainer");

一套简单、易用、并具备一定扩展能力和组合能力的统计图表库，基于图形语法理论搭建而成，『G2Plot』中的 G2 即意指图形语法 (the Grammar of Graphics)，同时也致敬了 ggplot2。我们想做的事有三件：

1. 使用户不用成为可视化专家也能够轻松制作出优雅美观的图表。
2. 保证图表能够经受得起业务的检验，在真实的场景中易用、好用。
3. 探索统计图表的更多可能性，使统计图表变得更好玩、更酷。

G2Plot 呈现给用户的是一套提炼自企业级产品的视觉语言和设计规范。不仅对图表的整体视觉样式进行了优化，并且针对每一个图表自身的特点，沉淀出一套最佳配置，保证用户能够通过最少的配置制作出优雅、标准的图表。

在现实的图表应用场景中，一个棘手的难题是图表的展示空间往往并不足够显示图表的数据量，造成极值情况下文本的重叠遮挡、内容无法自适应、内容裁剪等问题。G2Plot 借鉴宽容性设计的思想，在图表的信息密度过高时，对图表辅助信息进行抽稀，保证图表主要信息的展示和基本可读性。

在 G2Plot 体系下，图表不仅仅只是各不相关的实例，图层概念的引入提供了多图表组合、叠加、联动，共同讲述一个数据故事的可能性。未来，我们还将探索统计图表转化信息图的可能性，丰富统计图表的表现能力。

$ npm install @antv/g2plot

<div id="container"></div>

import { Bar } from '@antv/g2plot';
const data = [
  { year: '1951 年', sales: 38 },
  { year: '1952 年', sales: 52 },
  { year: '1956 年', sales: 61 },
  { year: '1957 年', sales: 145 },
  { year: '1958 年', sales: 48 },
];

const bar = new Bar(

Collection of TypeScript type challenges

English | 简体中文 | 日本語 | 한국어 | Português

by the power of TypeScript's well-known Turing Completed type system

High-quality types can help improve projects' maintainability while avoiding potential bugs.

There are a bunch of awesome type utility libraries that may boost your works on types, like ts-toolbelt, utility-types, SimplyTyped, etc., which you can already use.

This project is aimed at helping you better understand how the type system works, writing your own utilities, or just having fun with the challenges. We are also trying to form a community where you can ask questions and get answers you have faced in the real world - they may become part of the challenges!

Click the following badges to see details of the challenges.

Note: Challenges work in the strict mode.

Simple loading spinners animated with CSS. See demo. SpinKit only uses (transform and opacity) CSS animations to create smooth and easily customizable animations.

• Add spinkit.css or spinkit.min.css to your project (or copy-paste the CSS that you need for your spinner—there are no dependencies between spinners, no shared classes, and no shared animations, etc, so it should be fairly straight-forward to extract only the code that you need)
• Add a spinner to your project by copy-pasting HTML from spinkit.css or examples.html
• Add the sk-center utility class to the spinner to center it (it sets margin to auto)
• By default, the width and height of all spinners are set to 40px. background-color is set to #333.
• Configure the spinner by overwriting the CSS variables, primarily --sk-size (spinner width & height) and --sk-color (spinner color). If you need broader browser support, remove the CSS variables.

Custom React hooks allow developers to abstract the business logic of components into single, reusable functions.
I have noticed that many of the hooks I have created and shared across projects involve callbacks, references, events, and dealing with the component lifecycle.
Therefore, I have created beautiful-react-hooks, a collection of useful React hooks that may help other developers speed up their development process.
Moreover, I have strived to create a concise and practical API that emphasizes code readability, while keeping the learning curve as low as possible, making it suitable for larger teams to use and share t -- Please before using…

Many of the types here should have been built-in. You can help by suggesting some of them to the TypeScript project.

Either add this package as a dependency or copy-paste the needed types. No credit required. 👌

PR welcome for additional commonly needed types and docs improvements. Read the contributing guidelines first.
