This is my 14th 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.

I’m proud to say we have successfully translated 22% of the project on Crowdin!


Project Details

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.

Contribution Specifications

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.

Translation Overview

During this contribution I continued working on on v6. The Spanish team started to translate Node’s files of the v10, now we’re progressively moving to the version 6 of this awesome project. 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. talks about the Buffer class and all of its functions inside Node.js. I translated the sections: The --zero-fill-buffers command line option, What makes Buffer.allocUnsafe() and Buffer.allocUnsafeSlow() "unsafe"?, Buffers and Character Encodings, Buffers and TypedArray, Buffers and ES6 iteration and new Buffer(array).

When I searched for a clear definition of the Buffer class this is what I found on the official Node.js documentation:

…mechanism for reading or manipulating streams of binary data. The Buffer class was introduced as part of the Node.js API to make it possible to interact with octet streams.

Alright, I would love to say I understood that completely but sadly it took me a while to comprehend what that concept meant. I’ll explain it to you in parts:

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.

These are the web pages I read if you’re interested: 1, 2, 3, 4.

Here are some translations samples:


It is possible to create a new Buffer that shares the same allocated memory as a [TypedArray] instance by using the TypeArray object's .buffer property.


Es posible crear un nuevo Buffer que comparta la misma memoria asignada como un instancia [TypedArray] utilizando la propiedad .buffer del objeto TypeArray.


The Buffer.from() and [TypedArray.from()] have different signatures and implementations. Specifically, the [TypedArray] variants accept a second argument that is a mapping function that is invoked on every element of the typed array.


El Buffer.from() y el [TypedArray.from()] tienen diferentes firmas e implementaciones. Específicamente, las variantes de [TypedArray] aceptan un segundo argumento que es una función de mapeo que es invocada en cada elemento del array indicado.

Since the text is related to computer science it is very important to do some research before translating a word if you are not sure about its meaning. As a matter of fact, some words were left untranslated on purpose, otherwise, their true meaning would be lost in the translation.

I have worked as a translator for the project Da Vinci Polyglot and I am currently working as a language moderator for the Utopian + Da Vinci translation category.

And of course, I am part of the Spanish team!
