Hello,

This is my 19th contribution to Node.js. I’m currently translating this project into Spanish, along with an awesome group of translators and moderators from Utopian + Da Vinci, we are doing our best to do everything correctly. If you are interested in open-source projects, I encourage you to keep reading.

Node.js is a very extensive project, it may seem impossible to translate it completely, but the Spanish team is working really and we are slowly making progress. It’s currently at 31% on Crowdin:

<h3>Project Details</h3>

> Node.js is an open-source, cross-platform JavaScript run-time environment that executes JavaScript code outside of a browser. It achieves low latency and high throughput by taking a “non-blocking” approach to serving requests. Basically, Node.js can open, create, read, write, close and delete files on a server, using JavaScript. It also includes tasks that will be executed on certain servers.

_I know it can be a bit confusing at first, so let me explain it to you in simpler words:_

Let’s say you want to build a software to keep record of your company’s earnings. A feature where viewing your monthly earnings is updated live can be very useful. In that way, if one of your sales employees is busy, another employee could still be seeing the updates live, without reloading the page.

This has been done before using another technologies. However, Node.js is way faster and better. So, yes it is the best option for developers who want to build real-time applications where both the server and the client can exchange data freely with no restrictions.

<h3>Contribution Specifications</h3>

Being such an important project, Node.js is being translated to several languages so it can reach many people around the world. As it for me, I am contributing to the Spanish language.


<h3>Translation Overview</h3>

This is my 7th contribution to the folder  _**buffer.md**_ on v6 and I’m finally reaching its end. The Spanish team started to translate Node’s files of the v10, now we’re progressively moving to the version 6. Since I’m not a guru in computer science I had to read a lot before I could feel confident enough to translate the content of this folder, which is something you must regularly do while translating Node.js since it has many specific terms related to computer science.

_**buffer.md**_ talks about the Buffer class and all of its functions inside Node.js. This time I translated the methods: _buf.length, buf.readDoubleBE(offset[, noAssert]), buf.readDoubleLE(offset[, noAssert]), buf.readFloatBE(offset[, noAssert]), buf.readFloatLE(offset[, noAssert]), buf.readInt8(offset[, noAssert]), buf.readInt16BE(offset[, noAssert]), buf.readInt32BE(offset[, noAssert]), buf.slice([start[, end]]), buf.swap16(),_ and _buf.values()._

> In my [previous](https://steemit.com/utopian-io/@marugy99/spanish-translation-of-node-js-part-14-1029-words) contribution I explained how _streams are basically a sequence of data (normally bytes) being moved from one point to another over time. Binary data is the only type of data that can be executed by a computer and it’s represented in combinations of ones and zeros. And a Buffer is a portion of the memory that stores a stream that's then collected and stored in variables inside the same Buffer._

> _So the Buffer class is basically a “waiting area” for information! When Node.js receives data that’s not ready to be processed yet it will send it to the Buffer and store it there until it’s ready._

***

Like I’ve mentioned before, inside this folder there are all the Buffer methods with a brief explanation of how to use them, the values you have to use to active the method and an example of the code. Once you understand how they work it gets easier to translate the text.

This time there were several methods that were very simple and easy to understand, such as:

![1.PNG](https://cdn.steemitimages.com/DQmTJkQuu6tJZoRPWVuiPvw6cE8GdYjvmbriCZ5VAgPGRYV/1.PNG)

Just like you can see in the picture, this method returns an iterator object that contains the value of each byte inside a buffer object. In case you’re wondering, an iterator is an object that represents a stream of data, and that is able to traverse through elements in a container, normally lists and sets. 

Basically, an iterator allows programmers to process every element of a container while at the same time isolates the user from the internal structure of the container.

This short section could not be translated to Spanish because both sentences represent code values that belong to Node.js, therefore they would lose their true meaning and function if translated.

![2.PNG](https://cdn.steemitimages.com/DQmSYanjBLhzG5ekxvBdvEv9HY1Z7vBYAEtFyBRmRmVNoE2/2.PNG)

In simple words, this method writes the specified string into a buffer at the specified position, according to the character encoding. 

Inside the `length` parameter one must put the number of bytes to write into the buffer and lastly, it will return an integer that represents the number of bytes written.

Here’s how I translated that paragraph:

![DQmU4k8R9asoiB2q6MVP1v8LLRYDiUK753kqqsr7RLvfgyu.jpg](https://cdn.steemitimages.com/DQmPt78L24TT5n4ZGjYaLZpZP9PYZuVTy7yKgt9341489CF/DQmU4k8R9asoiB2q6MVP1v8LLRYDiUK753kqqsr7RLvfgyu.jpg)

![](https://cdn.steemitimages.com/DQmY94GarNnKgc4F3GQY3TxMM2oK2swbrLKoyMJWoq9q5ma/image.png)

ts purpose is to extract parts of a string and return the extracted parts inside a new string. The `start` parameter represents the position where to begin the extraction, and the `end` parameter represents where to finish the extraction. According to the documentation of Node.js, if `end` it’s not specified this method will select all the characters from the start-position to the end of the string.

Here’s how I translated that paragraph:

There was one particular term that was mentioned several time during this contribution: **JSON**. It stands for “JavaScript Object Notation” and it’s used to transmit human-readable data objects and array data types between servers and web applications. It was first conceived in 2000 by Douglas Crockford and it was derived from JavaScript.

<h4>Here are some other translation samples:</h4>

**English:**

_Setting `noAssert` to true allows `offset` to be beyond the end of `buf`, but the resulting behavior is undefined._

**Spanish:**

_Configurar `noAssert ` a true permite que `offset ` esté más allá del final de `buf`, pero el comportamiento resultante es indefinido._

**English:**

_Reads `byteLength` number of bytes from `buf` at the specified `offset` and interprets the result as an unsigned integer. Supports up to 48 bits of accuracy._

**Spanish:**

_Lee el número de bytes `byteLength` desde `buf` en el `offset` especificado e interpreta el resultado como un entero sin signo. Soporta hasta 48 bits de precisión._

Some words and code values were left untranslated on purpose, otherwise, their true meaning would be lost in the translation.
