JavaScript：世界上误解最深的语言[1] 以下文字资料是由(全榜网网www.cha138.com)小编为大家搜集整理后发布的内容，让我们赶快一起来看一下吧！

　　JavaScript aka Mocha aka LiveScript aka JScript aka ECMAScript is one of the world s most popular programming languages Virtually every personal puter in the world has at least one JavaScript interpreter installed on it and in active use JavaScript s popularity is due entirely to its role as the scripting language of the WWW

　　JavaScript 或者叫 Mocha 或者叫 LiveScript 或者叫 JScript 又或者叫 ECMAScript 是世界上最流行的编程语言之一事实上世界上的每一台个人电脑都安装并在频繁使用至少一个JavaScript解释器 JavaScript的流行完全是由于他在WWW脚本语言领域中的地位决定的

　　Despite its popularity few know that JavaScript is a very nice dynamic object oriented general purpose programming language How can this be a secret? Why is this language so misunderstood?

　　尽管它很流行但是很少有人知道JavaScript是一个非常棒的动态面向对象通用编程语言这居然能成为一个秘密！这门语言为什么被误解如此之深？

　　The Name　　名字

　　The Java prefix suggests that JavaScript is somehow related to Java that it is a subset or less capable version of Java It seems that the name was intentionally selected to create confusion and from confusion es misunderstanding JavaScript is not interpreted Java Java is interpreted Java JavaScript is a different language

　　Java 前缀很容易使人联想到Java 并认为它是Java的子集或简化版的Java 看起来最初给它选这个名字是别有用心的是故意混淆概念故意制造误解的 JavaScript不是解释执行的Java Java是解释执行的Java JavaScript是另外一种语言

　　JavaScript has a syntactic similarity to Java much as Java has to C But it is no more a subset of Java than Java is a subset of C It is better than Java in the applications that Java (fka Oak) was originally intended for

JavaScript的语法和Java有相似之处这就像Java的语法和C很相像一样但是它不是Java的子集就像Java不是C的子集一样它在Java（Oak）最初打算进军的领域中比Java更好

　　JavaScript was not developed at Sun Microsystems the home of Java JavaScript was developed at Netscape It was originally called LiveScript but that name wasn t confusing enough

　　JavaScript不是Sun Microsystems的产品 Sun是Java的家 JavaScript是在Netscape被开发出来的它最初叫LiveScript 嗯……还是这个名字好

　　The Script suffix suggests that it is not a real programming language that a scripting language is less than a programming language But it is really a matter of specialization Compared to C JavaScript trades performance for expressive power and dynamism

　　 Script后缀让人认为他不是一门真正的编程语言和一门编程语言还有相当的差距但是这只是应用领域的问题和C相比 JavaScript是牺牲了性能但换来了丰富的表现力和灵活的形态

　　Lisp in C s Clothing　　披着C皮的Lisp

　　JavaScript s C like syntax including curly braces and the clunky for statement makes it appear to be an ordinary procedural language This is misleading because JavaScript has more in mon with functional languages like Lisp or Scheme than with C or Java It has arrays instead of lists and objects instead of property lists Functions are first class It has closures You get lambdas without having to balance all those parens

　　JavaScript的类C语法包括大括号和语句的形式让它看起来像普通的面向过程编程语言这是一种误解因为JavaScript和函数式语言比如 Lisp 或 Scheme 有更多的相似之处而不是和C或Java 它使用数组而不是列表使用对象而不是属性列表函数是第一位的它有闭包（closures 怎么翻译？？）另外你还可以使用lambda表达式

　　Typecasting　　类型转换

　JavaScript was designed to run in Netscape Navigator Its success there led to it being standard equipment in virtually all web browsers This has resulted in typecasting JavaScript is the Gee Reeves of programming languages JavaScript is well suited to a large class of non Web related applications

　　JavaScript最初被设计成在Netscape Navigator中运行它在Navigator中的成功引领它成为事实上所有web浏览器的标准装备这就造就了类型转换 JavaScript是编程语言中的 Gee Reeves（超人）是大量非web程序的称职之选

　　Moving Target　　移动靶

　　The first versions of JavaScript were quite weak They lacked exception handling inner functions and inheritance In its present form it is now a plete object oriented programming language But many opinions of the language are based on its immature forms

　　JavaScript的最初几版非常弱没有异常处理没有内部函数和继承现如今它已经成为完全面向对象的编程语言但是这门语言的许多思想是基于它不成熟的形式的
