This article mainly introduces the basic concepts of Node, which has certain reference value. Now I share it with everyone. Friends in need can refer to it

Preface

1. javascript Birth

Brendan Eich is the father of JavaScript. The first reason he entered Netscape was to engage in the development of Scheme, but he received a task that he didn't like very much. However, due to the urgent need, the father of js completed the design of javascript in just 10 days. , the project codename is Mocha, and it was originally named LiveScript.

javascript draws on different features of other languages, such as functional style, prototype chain inheritance, etc. It eventually got its own name javascript due to being in the shadow of java at the time.

Many people cannot distinguish the relationship between java and javascript. Their relationship is like the relationship between Lei Feng and Leifeng Pagoda.

2. The development of javascript and the emergence of Node

In the first browser war, Microsoft added its scripting language JScript to IE3.0, which is fully compatible with javascript. In early 1997 JScript has been added to its server IIS 3.0. This is the scripting language we can use in ASP.

In view of Microsoft's opposition to Netscape, Netscape standardized JavaScript in 1996 and submitted it to the ECMA international standards organization in November. And in June 1997, the first version of javascript was launched, ECMA-262, also known as ECMAScript.

The fact that javascript can run on the server side was gradually forgotten until Node relied on the high performance of V8 and asynchronous I/O, reappears in people’s sight.
