- What is Node?

The Node environment comprises everything you need to run a program written in JavaScript(JS).

Node.js first started when the original developers of JS extended its functionalities from something you could only run in the browser to something you could execute on your computer as a independent application.

Now you can do much more with JavaScript than just creating interactive websites and web apps. Modern JavaScript has the same capabilites as other scripting languages like Python, and therefore it can do the same as these.

Both your browser's JavaScript and Node.js environment run on the V8 JavaScript runtime engine. This engine takes your JS code and converts it into a much faster machine code (machine code is a low level code that the computer can execute without needing to first interpret it).

- Translation Overwiew

In this section, my translation was focused on the guides related to the Buffer functionalities, specifically on the Class Buffer building commands and the allocation and Management of the system's memory for the Buffer. The documentation is also related with the encoding parameters and methods used on Node.js

- Examples sentences in Spanish:

• However, in the case where a developer may need to retain a small chunk of memory from a pool for an indeterminate amount of time, it may be appropriate to create an un-pooled <0>Buffer</0> instance using <0>Buffer.allocUnsafeSlow()</0> and then copying out the relevant bits.

  • Sin embargo, en el caso donde un desarrollador puede necesitar retener un pequeño pedazo de memoria desde un conjunto por una cantidad indeterminada de tiempo, puede ser apropiado crear una instancia de Buffer sin agrupar utilizando Buffer.allocUnsafeSlow() y luego copiando los bits relevantes.

• Note that the <0>Buffer</0> module pre-allocates an internal <0>Buffer</0> instance of size [<0>Buffer.poolSize</0>] that is used as a pool for the fast allocation of new <0>Buffer</0> instances created using [<0>Buffer.allocUnsafe()</0>] and the deprecated <0>new Buffer(size)</0> constructor only when <0>size</0> is less than or equal to <0>Buffer.poolSize >> 1</0> (floor of [<0>Buffer.poolSize</0>] divided by two).

  • Tenga en cuenta que el módulo Buffer asigna previamente una instancia de Buffer interna de tamaño [Buffer.poolSize] que es usado como un repositorio para la rápida asignación de las nuevas instancias de Buffer creadas utilizando [Buffer.allocUnsafe()] y el constructor obsoleto new Buffer(size) solo cuando size es menor o igual que Buffer.poolSize >> 1 (piso de [Buffer.poolSize] dividido entre dos).

• Calling [<0>Buffer.alloc()</0>] can be significantly slower than the alternative [<0>Buffer.allocUnsafe()</0>] but ensures that the newly created <0>Buffer</0> instance contents will <1>never contain sensitive data</1>.

  • Llamar a [<0>Buffer.alloc()</0>] puede ser significativamente más lento que la alternativa [<0>Buffer.allocUnsafe()</0>] pero garantiza que el contenido de la instancia de <0>Buffer</0> creada recientemente <1>nunca contendrá datos confidenciales</1>.
