请各位大大轻拍,一直搞不懂JavaScript和其他高级语言(Java,PHP等)的区别,然后突然想到是不是因为Java和PHP都会不断升级,发布新的版本,而JavaScript没有呢?
我了解他们的主要区别肯定不是这个,但是不是有点关系?还有就是JavaScript是不是出来之后就一直没变过?
新手疑惑,网上也没查出个所以然,望解答。

最近看到了这个,感觉有点帮助:
"After its adoption outside of Netscape, a standard document was written to describe the way the JavaScript language should work to make sure the various pieces of software that claimed to support JavaScript were actually talking about the same language. This is called the ECMAScript standard, after the Ecma International organization that did the standardization. In practice, the terms ECMAScript and JavaScript can be used interchangeably—they are two names for the same language."
有啊,除开版本号以外,还有实现上的不同。 点我
