Node.js Translation to Spanish - ( 1118 words) (Part-76)

Repository

Project Details

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

Node.js came into existence when the original developers of JavaScript extended it from something you could only run in the browser to something you could run on your machine as a standalone application.

In simple words, it's an open source execution environment for developing web applications, which is event-based, it uses the V8 engine to provide an execution environment that compiles and executes JavaScript at a higher speed. It is possible to run Node.js without any restriction on Windows, Linux and Mac OS X.

It should be noted that it is NOT a server language, this means that it executes code, so it could be understood as an interpreter.

Contribution Specifications

Node.js is currently being translated into 33 languages. I'm contributing to translate it into the Spanish language.

So far, we have managed to translate 74% of the project!

Translation Overview

For this occasion I translated the folder Perf_hooks.md. The Performance Timing API, allows developers to take precise measurements of the effects of userland code in the event loop and how that affects the performance of your application.

Basically, if you want to measure the performance of your app in a serious manner, you’ll want to read about perf_hooks at some point.

To put it simply, with this module you can perform actions at different stages of the life of a callback function.

As an example of the work done, I will use part of the section Class: Performance:

English:

`performance.measure`(name, startMark, endMark)

Creates a new PerformanceMeasure entry in the Performance Timeline. A PerformanceMeasure is a subclass of PerformanceEntry whose performanceEntry.entryType is always measure, and whose performanceEntry.duration measures the number of milliseconds elapsed since startMark and endMark.

The startMark argument may identify any existing PerformanceMark in the Performance Timeline, or may identify any of the timestamp properties provided by the PerformanceNodeTiming class. If the named startMark does not exist, then startMark is set to [timeOrigin][] by default.

The endMark argument must identify any existing PerformanceMark in the Performance Timeline or any of the timestamp properties provided by the PerformanceNodeTiming class. If the named endMark does not exist, an error will be thrown.
performance.node

Spanish:

`performance.measure`(name, startMark, endMark)

Crea una nueva entrada PerformanceMeasure en la Línea de Tiempo de Rendimiento. Una PerformanceMeasure es una subclase de PerformanceEntry cuyo performanceEntry.entryType es siempre measure, y cuya performanceEntry.duration mide el número de milisegundos transcurridos desde startMark y endMark.

El argumento startMark puede identificar cualquier PerformanceMark existente en la Línea de Tiempo de Rendimiento, o puede identificar cualquiera de las propiedades timestamp proporcionadas por la clase PerformanceNodeTiming. Si el nombre startMark no existe, entonces startMark es establecido como [timeOrigin][] por defecto.

El argumento endMark debe especificar cualquier PerformanceMark existente en la Línea de Tiempo de Rendimiento o cualquiera de las propiedades timestamp proporcionadas por la clase PerformanceNodeTiming. Si el endMark nombrado no existe, se producirá un error.
