Node.js was created by researcher Ryan Dahl in 2009 during an analysis of web pages and how they worked.
Ryan realized that applications were being used inefficiently and that the way users interacted with machine resources consumed more processing power than necessary.
In a traditional web application, request overload is common, which often leads to blocking due to file loading or heavy processing. That’s why the researcher understood the need to create Node.js.
The fact that Node is single-threaded is a differentiator in development. It uses what are called execution flows, which simplifies handling demand and avoids interruption.
Built on V8 Engine technology and JavaScript, with the purpose of accelerating application performance, Node.js is portable across Windows, Mac, and Linux, making it possible to build different web applications using only JavaScript.
Therefore, the demands that arise from the internet and the way JavaScript code can be built provide countless possibilities for web development. Node.js becomes a collaborative and agile platform with the following characteristics:
- Responds to application requests
- Free technology with no licensing
- Front-end and Back-end
- Open source: enables an active community that contributes to the project
- JavaScript programming: a popular language on the web
- Performance: low memory usage and efficient CPU utilization
Over the last decades, with the “browser wars”, the internet became increasingly competitive, expanding the field of information.
In this context, Tim Berners-Lee created the first browser, called WorldWideWeb, in 1990. Beyond being a computer scientist, he was one of the pioneers in the use of hypertext with the goal of sharing information.
As information expanded, software was needed to enable people to search for it. Different browsers emerged, and in a world like this, being online means being informed.
Chronology
This chronology aims to present the history and advances of technology since the browser wars:
1993 – Mosaic appears as the first to run on Windows, allowing web access for the general public.
1994 – Netscape brings features that a modern browser offers: tabs, browsing history, and more.
1995 – Explorer 1.0: Microsoft enters the market and soon updates it.
1996 – Microsoft releases Explorer 3.0, and in 1997 the fourth version is announced.
1998 – With source code release, Netscape creates Mozilla.
2000 – With a loyal community, Opera is developed as an alternative browser.
2003 – Apple announces its browser, Safari, the default for its operating system and still used today.
2004 – Firefox 1.0 emerges as an updated version of Mozilla.
2008 – Google finally presents its project: fast, secure, and stable compared to competitors, promising to reduce blocking.
With Google’s releases, V8 became the JavaScript engine (virtual machine) used in Google Chrome and in Node.js, delivering fast performance as a result of the browser race, boosting back-end processing.
