#### Project Details

>Node.js is an open-source, cross-platform JavaScript run-time environment that executes JavaScript code outside of a browser. 


Initially, it is notice that Node.js is not a JS application, but a JS runtime platform. Node.js is written in C++ and is a Javascript runtime environment. Why use C++? According to Ryan Dahl, founder of Node.js, he initially wanted to use Ruby to write Node.js, but later found that the performance of the Ruby virtual machine could not meet his requirements. Later he tried to use the V8 engine, so he chose the C++ language. Since it is not a Javascript application, why is it called .js? Because Node.js is a Javascript runtime environment.

Node.js uses the V8 engine of Google Chrome browser, which has good performance, and also provides many system-level APIs, such as file operation and network programming. The Javascript code on the browser side is subject to various security restrictions at runtime and has limited operation on the client system. In contrast, Node.js is a comprehensive background runtime that provides Javascript with many of the features that other languages can implement.

#### Translation Overview

The project has 1,048,910 words with 1,048,272 words translatable as shown in below figure, it has 592,607 duplicate words in this project. Although there are large number of translatable words in this project, most of them are the original codes as examples to indicate how to use Node.js.

As shown in above figure, the translation project has 33 target languages, I work on simplified Chinese translation.  There are many sub-folders under this project,  some files include several program examples as the guide to show how to use Node.js, I will not touch these codes during my translating works in order to clearly count the number of words I contribute. 

This is my fifth contribution for Node.js translation project, since the total number of words in this project is too huge,  it is not easy to check the work in the whole progress bar.  As shown in below figure, after I translated **1,051 + 1,035+1,128+1,105 + 1,162 = 5,481** words in total, the progress bar reaches 1%.

#### Word count details

This is my fifth contribution for the project,  as shown in the top member report generated by Crowdin, I contributed 1,156 words in this time.   The below figure verifies the number I contributed in this time.

As a cross validation, before and after screenshot of the single file I translated as shown in below. They illustrate the number of words I translated before and after my work. Therefore, the number of words I contributed is 2,973 - 1,811 = 1,162. The difference between this number and the one reported in top member report is that I overlapped one existing translated item, because I think I can provide more accurate translation.
