hello world作为所有编程语言的起始阶段,占据着无法改变的地位,所有中/英/法/德/美……版本的编程教材中,hello world总是作为第一个TEST记录于书本之中,所有的编程第一步就在于此了!经典之中的经典!
hello world!
"Hello, world"程序是指在计算机屏幕上输出Hello, world这行字符串的计算机程序,“hello, world”的中文意思是“世界,你好”。这个例程在Brian Kernighan和Dennis M. Ritchie合著的The C Programming Language中被使用而广泛流行。因为它的简洁、实用,并包含了一个程序所应具有的一切,因此为后来的编程类图书的作者提供了范例,一直待续到今。

JavaScript
JavaScript是一种脚本语言。最广泛用于HTML文件中,也可以用在其它宿主环境下,比如Microsoft Windows 脚本宿主(WSH)和一些Web服务环境。
用于HTML中:
alert("Hello, World!");
//或者
document.write("Hello, World!");
用于WSH中:
WScript.Echo("Hello, World!");
