如Google框架MapReduce；MR描述了一种使用Map功能实现并行性的方法，它将大型数据分割成多个键-值对。
The map function, originating in functional languages like Lisp but now common in many other languages, is an application of a function over a list of elements.
map函数，源于功能性语言（如 Lisp）但如今在其他语言中也很常见，其中包含了一系列元素的函数的应用程序。

The map function is designed to take a large data input and divide it into smaller pieces, which it then hands off to other processes that can do something with it.
map函数专用于获取大数据输入，并将其分成小片段，然后交由其他进程进行操作。
The third argument, rereduce, has to do with whether or not this reduce function is operating on aggregate information or the raw results from the map (the ones from the map function).
第三个参数是rereduce，这个参数必须处理这个reduce函数是在汇总信息上操作还是在来自映射的原始结果（来自map 函数的结果）上操作。
The map function is similar to filter , except that instead of removing some elements, it replaces every element with a user-specified transformation of its original value. The syntax is.
map函数类似于filter，与后者不同的是它不是删除部分元素，而是使用用户指定的原始值转换替换每个元素。
I then append a new collection onto factors - generated by the map function on the factors list - applying the code to generate the symmetrical (the matching factor above the square root) list.
然后我将一个新的集合附加至由factor列表中的map函数生成的factor上，应用此代码生成对称的(平方根上方匹配的因子)列表。
The map function would be used where a new array was to be created, leaving the original array contents untouched, which is actually the way most functional programmers would prefer to operate.
