随着FCC中文社区的快速发展和更多小伙伴的崛起，此项目已从个人项目升级到团队项目。详情请移步：

freecodecamp.cn

欢迎来到freecodecamp中文社区(https://freecodecamp.cn)

freecodecamp是什么？

freecodecamp 是一个自由的开源编程社区，它致力于抹平教育差距，

让像你我一样的平凡人也能享受到花费巨资才可能享受到的优质教育。

freecodecamp的特点

freecodecamp最大的特点是它本身就是个开源项目。

我们不仅可以在freecodecamp上学习，还可以利用所学的知识来把freecodecamp建设得更好。

学编程的都知道编程语言之间的区别很大程度上体现在语言本身是否能完成自举。

对于语言来说，自举分为3个层次：

1、调用--自己调用自己（编程语言中常见的递归操作）

2、改进--自己改进自己（编程语言的更新迭代）

3、实现--自己实现自己（实现编程语言自己的解释器或编译器）

对于个人来说，自举也分为3个层次：

1、调用--自己调用自己的独立思考能力、自学能力。

2、改进--自己经常review自己，意识到自己的不足，勇敢走出自己的舒适区。

3、实现--做一个作品来证明自己的能力，实现自己的人生价值。

为什么要创建freecodecamp中文社区？

freecodecamp发展速度太快了，从1月五万star到3月排第二，现在已经超越bootstrap成为github上star最多的项目了。

github这个全球最大的编程社交网站上诞生了全球最大的编程学习网站freecodecamp。

我和各位小伙伴一样都先在freecodecamp英文社区上学习，

我用谷歌翻译和有道词典来解决英文问题，看得非常吃力、理解得也有些生硬，学习效率较低。

当我学到Counting Cards（21点算法）时，发现英文的讲解怎么也看不懂，在网上查找大量资料后，我才搞明白。

我瞬间产生了建立freecodecamp中文社区的念头，

这样许多同学就可以少走很多弯路，直接获取最有效的学习路径。

My code:

var myStr; // Change this line
myStr ="\\ \t \t \r \n"; 

这个挑战我花了至少30分钟，然后才写出来这个挑战的代码。
首先我在 ""这个问题上花了20分钟，可能是因为我的粗心，没看清要求造成的。
其次在是难在 \t \t这个问题上，因为我把它写成了一个，你们设置是写成了2个。 我没有说你们设计这个题目不好，只是我感觉你们如果把 \t \t改成 \t 会让学习者更加容易理解。 感觉你们的付出。

关于design-a-danmu-app的建议

这个项目的演示http://codepen.io/huluoyang/pen/GZbBwL

已经在Settings里提前引入了野狗的js，建议提示出来。
不然刚刚接触很容易懵圈= =。
还有在注释里面给出野狗的官方开发文档的地址，引导阅读。
这样对新手要要友好很多。

欢迎加入FCC中文社区！

翻译是个挺花费精力的事情，我一个人也不可能有时间翻译完整个课程。
所以我只是搭台，请你们来唱戏。
至于戏能唱得有多精彩，全靠你们自己的发挥。
这是个兴趣驱动的社区，你可以做任何你能想到的事情。
课程翻译、网站翻译、修改源代码、添加国内CDN、提升性能等等。

    });

    return newArr;

    for (var i = 0; i <= arr.length; i++) {

    }

在大家心目中，猫是慵懒的可爱的化身，它可以睡饱了再起来吃饭，可以逗趣小耗子，可以卖得了萌，使得了坏，这样百变的小怪兽就集结在一只宠物上，怎能不惹人怜爱。

养动物有的时候，就是介于爱与恨之间，当你钦羡别人萌宠这么可爱的时候，你一定没有想过，狗狗和猫猫会到处拉屎，甚至会屯老鼠，啃鞋子，用爪子爬门，你不理它，它就挠你，你要对它发脾气，它会比你更来劲。所以，狗猫慎入，没有一定的准备，切勿随便去侍养动物。它们一旦认定你了，你就是它们的主人，如果你抛弃它们，它们必定心中重创。
