Javascript语言的设计不够严谨，很多地方一不小心就会出错。举例来说，请考虑以下情况。现在，我们要判断一个全局对象myObj是否存在，如果不存在，就对它进行声明。用自然语言描述的算法如下：复制代码代码如下:if (myObj不存在){ 声明myObj; }你可能会觉得，写出这段代码很容易。但是实际上，它涉及的语法问题，远比我们想象的复杂。Juriy Zaytsev指出，判断一个Javascript对象是否存在，有超过50种写法。只有对Javascript语言的实现细节非常清楚，才可能分得清它们的区别。第一种写法根据直觉，你可能觉得可以这样写：复制代码代码如下:if (!myObj) { myObj = { }; }但是，运行这段代码，浏览器会直接抛出ReferenceError错误，导致运行中断。请问错在哪里？对了，if语句判断myObj是否为空时，这个变量还不存在，所以才会报错。改成下面这样，就能正确运行了。复制代码代码如下:if (!myObj) { var myObj = { }; }为什么加了一个var以后，就不报错了？难道这种情况下，if语句做判断时，myObj就已经存在了吗？要回答这个问题，就必须知道Javascript解释器的工作方式。Javascript语言是"先解析，后运行"，解析时就已经完成了变量声明，所以上面的代码实际等同于：复制代码代码如下:var myObj; if (!myObj) { var myObj = { }; }因此，if语句做判断时，myObj确实已经存在了，所以就不报错了。这就是var命令的"代码提升"（hoisting）作用。Javascript解释器，只"提升"var命令定义的变量，对不使用var命令、直接赋值的变量不起作用，这就是为什么不加var会报错的原因。第二种写法除了var命令，还可以有另一种改写，也能得到正确的结果：复制代码代码如下:if (!window.myObj) { myObj = { }; }window是javascript的顶层对象，所有的全局变量都是它的属性。所以，判断myobj是否为空，等同于判断window对象是否有myobj属性，这样就可以避免因为myObj没有定义而出现ReferenceError错误。不过，从代码的规范性考虑，最好还是对第二行加上var：复制代码代码如下:if (!window.myObj) { var myObj = { }; } 或者写成这样： if (!window.myObj) { window.myObj = { }; }第三种写法上面这种写法的缺点在于，在某些运行环境中（比如V8、Rhino），window未必是顶层对象。所以，考虑改写成：复制代码代码如下:if (!this.myObj) { this.myObj = { }; }在全局变量的层面中，this关键字总是指向顶层变量，所以就可以独立于不同的运行环境。第四种写法但是，上面这样写可读性较差，而且this的指向是可变的，容易出错，所以进一步改写：复制代码代码如下:var global = this; if (!global.myObj) { global.myObj = { }; }用自定义变量global表示顶层对象，就清楚多了。第五种写法还可以使用typeof运算符，判断myObj是否有定义。复制代码代码如下:if (typeof myObj == "undefined") { var myObj = { }; }这是目前使用最广泛的判断javascript对象是否存在的方法。第六种写法由于在已定义、但未赋值的情况下，myObj的值直接等于undefined，所以上面的写法可以简化：复制代码代码如下:if (myObj == undefined) { var myObj = { }; }这里有两个地方需要注意，首先第二行的var关键字不能少，否则会出现ReferenceError错误，其次undefined不能加单引号或双引号，因为这里比较的是undefined这种数据类型，而不是"undefined"这个字符串。第七种写法上面的写法在"精确比较"（===）的情况下，依然成立：复制代码代码如下:if (myObj === undefined) { var myObj = { }; }第八种写法根据javascript的语言设计，undefined == null，所以比较myObj是否等于null，也能得到正确结果：复制代码代码如下:if (myObj == null) { var myObj = { }; }不过，虽然运行结果正确，但是从语义上看，这种判断方法是错的，应该避免。因为null指的是已经赋值为null的空对象，即这个对象实际上是有值的，而undefined指的是不存在或没有赋值的对象。因此，这里只能使用"比较运算符"（==），如果这里使用"精确比较运算符"（===），就会出错。第九种写法还可以使用in运算符，判断myObj是否为顶层对象的一个属性：复制代码代码如下:if (!("myObj" in window)) { window.myObj = { }; }第十种写法最后，使用hasOwnProperty方法，判断myObj是否为顶层对象的一个属性：复制代码代码如下:if (!this.hasOwnProperty("myObj")) { this.myObj = { }; }总结1. 如果只判断对象是否存在，推荐使用第五种写法。2. 如果除了对象是否存在，还要判断对象是否有null值，推荐使用第一种写法。

很多语言中都有块级作用域，但JS没有，它使用var声明变量，以function来划分作用域，大括号“{}” 却限定不了var的作用域。用var声明的变量具有变量提升（declaration hoisting）的效果。ES6里增加了一个let，可以在{}， if， for里声明。用法同var，但作用域限定在块级，let声明的变量不存在变量提升。

今天小编要跟大家分享的文章是关于Web前端工程师应该知道的JavaScript的10个难点。相信很多正在学习Web前端知识的小伙伴对于JavaScript存在很多疑问，为了帮助大家更好的学习Web前端知识，成为一名优秀的web前端工程师，今天小编为大家分享了这篇Web前端应该知道的JavaScript难点的问题，下面我们一起看一看吧！1、立即执行函数立即执行函数，即ImmediatelyInvokedFunctionExpression(IIFE)，正如它的名字，就是创建函数的同时立即执行。它没有绑定任何事件，也无需等待任何异步操作：1.(function(){2.3.//代码4.5.//...6.7.})();function(){}是一个匿名函数，包围它的一对括号将其转换为一个表达式，紧跟其后的一对括号调用了这个函数。立即执行函数也可以理解为立即调用一个匿名函数。立即执行函数最常见的应用场景就是：将var变量的作用域限制于你们函数内，这样可以避免命名冲突。2、闭包对于闭包(closure)，当外部函数返回之后，内部函数依然可以访问外部函数的变量。1.(function(){2.3.//代码4.5.//...6.7.})();代码中，外部函数f1只执行了一次，变量N设为0，并将内部函数f2赋值给了变量result。由于外部函数f1已经执行完毕，其内部变量N应该在内存中被清除，然而事实并不是这样：我们每次调用result的时候，发现变量N一直在内存中，并且在累加。为什么呢?这就是闭包的神奇之处了!3、使用闭包定义私有变量通常，JavaScript开发者使用下划线作为私有变量的前缀。但是实际上，这些变量依然可以被访问和修改，并非真正的私有变量。这时，使用闭包可以定义真正的私有变量：1.functionProduct(){2.3.varname;4.5.this.setName=function(value){6.name=value;7.};8.9.this.getName=function(){10.returnname;11.};12.}13.14.varp=newProduct();15.p.setName("Fundebug");16.17.console.log(p.name);//输出undefined18.console.log(p.getName());//输出Fundebug代码中，对象p的的name属性为私有属性，使用p.name不能直接访问。4、prototype每个JavaScript构造函数都有一个prototype属性，用于设置所有实例对象需要共享的属性和方法。prototype属性不能列举。JavaScript仅支持通过prototype属性进行继承属性和方法。1.functionRectangle(x,y)2.{3.this._length=x;4.this._breadth=y;5.}6.7.Rectangle.prototype.getDimensions=function()8.{9.return{10.length:this._length,11.breadth:this._breadth12.};13.};14.15.varx=newRectangle(3,4);16.vary=newRectangle(4,3);17.18.console.log(x.getDimensions());//{length:3,breadth:4}19.console.log(y.getDimensions());//{length:4,breadth:3}代码中，x和y都是构造函数Rectangle创建的对象实例，它们通过prototype继承了getDimensions方法。5、模块化JavaScript并非模块化编程语言，至少ES6落地之前都不是。然而对于一个复杂的Web应用，模块化编程是一个最基本的要求。这时，可以使用立即执行函数来实现模块化，正如很多JS库比如jQuery以及我们Fundebug都是这样实现的。1.varmodule=(function(){2.varN=5;3.4.functionprint(x){5.console.log("Theresultis:"+x);6.}7.8.functionadd(a){9.varx=a+N;10.print(x);11.}12.13.return{14.description:"Thisisdescription",15.add:add16.};17.})();18.19.20.console.log(module.description);//输出"thisisdescription"21.22.module.add(5);//输出“Theresultis:10”所谓模块化，就是根据需要控制模块内属性与方法的可访问性，即私有或者公开。在代码中，module为一个独立的模块，N为其私有属性，print为其私有方法，decription为其公有属性，add为其共有方法。6、变量提升JavaScript会将所有变量和函数声明移动到它的作用域的最前面，这就是所谓的变量提升(Hoisting)。也就是说，无论你在什么地方声明变量和函数，解释器都会将它们移动到作用域的最前面。因此我们可以先使用变量和函数，而后声明它们。但是，仅仅是变量声明被提升了，而变量赋值不会被提升。如果你不明白这一点，有时则会出错：1.console.log(y);//输出undefined2.3.y=2;//初始化y上面的代码等价于下面的代码：1.vary;//声明y2.3.console.log(y);//输出undefined4.5.y=2;//初始化y为了避免BUG，开发者应该在每个作用域开始时声明变量和函数。7、柯里化柯里化，即Currying，可以是函数变得更加灵活。我们可以一次性传入多个参数调用它;也可以只传入一部分参数来调用它，让它返回一个函数去处理剩下的参数。1.varadd=function(x){2.returnfunction(y){3.returnx+y;4.};5.};6.7.console.log(add(1)(1));//输出28.9.varadd1=add(1);10.console.log(add1(1));//输出211.12.varadd10=add(10);13.console.log(add10(1));//输出11代码中，我们可以一次性传入2个1作为参数add(1)(1)，也可以传入1个参数之后获取add1与add10函数，这样使用起来非常灵活。8、apply，call与bind方法JavaScript开发者有必要理解apply、call与bind方法的不同点。它们的共同点是第一个参数都是this，即函数运行时依赖的上下文。三者之中，call方法是最简单的，它等价于指定this值调用函数：1.varuser={2.name:"RahulMhatre",3.whatIsYourName:function(){4.console.log(this.name);5.}6.};7.8.user.whatIsYourName();//输出"RahulMhatre",9.10.varuser2={11.name:"NehaSampat"12.};13.14.user.whatIsYourName.call(user2);//输出"NehaSampat"·apply方法与call方法类似。两者唯一的不同点在于，apply方法使用数组指定参数，而call方法每个参数单独需要指定：·apply(thisArg,[argsArray])1.varuser={2.greet:"Hello!",3.greetUser:function(userName){4.console.log(this.greet+""+userName);5.}6.};7.8.vargreet1={9.greet:"Hola"10.};11.12.user.greetUser.call(greet1,"Rahul");//输出"HolaRahul"13.user.greetUser.apply(greet1,["Rahul"]);//输出"HolaRahul"使用bind方法，可以为函数绑定this值，然后作为一个新的函数返回：1.varuser={2.greet:"Hello!",3.greetUser:function(userName){4.console.log(this.greet+""+userName);5.}6.};7.8.vargreetHola=user.greetUser.bind({greet:"Hola"});9.vargreetBonjour=user.greetUser.bind({greet:"Bonjour"});10.11.greetHola("Rahul")//输出"HolaRahul"12.greetBonjour("Rahul")//输出"BonjourRahul"9、memoizationMemoization用于优化比较耗时的计算，通过将计算结果缓存到内存中，这样对于同样的输入值，下次只需要中内存中读取结果。1.functionmemoizeFunction(func)2.{3.varcache={};4.returnfunction()5.{6.varkey=arguments[0];7.if(cache[key])8.{9.returncache[key];10.}11.else12.{13.varval=func.apply(this,arguments);14.cache[key]=val;15.returnval;16.}17.};18.}19.20.21.varfibonacci=memoizeFunction(function(n)22.{23.return(n===0||n===1)?n:fibonacci(n-1)+fibonacci(n-2);24.});25.26.console.log(fibonacci(100));//输出35422484817926200000027.console.log(fibonacci(100));//输出354224848179262000000代码中，第2次计算fibonacci(100)则只需要在内存中直接读取结果。10、函数重载所谓函数重载(methodoverloading)，就是函数名称一样，但是输入输出不一样。或者说，允许某个函数有各种不同输入，根据不同的输入，返回不同的结果。凭直觉，函数重载可以通过if...else或者switch实现，这就不去管它了。jQuery之父JohnResig提出了一个非常巧(bian)妙(tai)的方法，利用了闭包。从效果上来说，people对象的find方法允许3种不同的输入:0个参数时，返回所有人名;1个参数时，根据firstName查找人名并返回;2个参数时，根据完整的名称查找人名并返回。难点在于，people.find只能绑定一个函数，那它为何可以处理3种不同的输入呢?它不可能同时绑定3个函数find0,find1与find2啊!这里的关键在于old属性。由addMethod函数的调用顺序可知，people.find最终绑定的是find2函数。然而，在绑定find2时，old为find1;同理，绑定find1时，old为find0。3个函数find0,find1与find2就这样通过闭包链接起来了。根据addMethod的逻辑，当f.length与arguments.length不匹配时，就会去调用old，直到匹配为止。1.functionaddMethod(object,name,f)2.{3.varold=object[name];4.object[name]=function()5.{6.//f.length为函数定义时的参数个数7.//arguments.length为函数调用时的参数个数8.if(f.length===arguments.length)9.{10.returnf.apply(this,arguments);11.}12.elseif(typeofold==="function")13.{14.returnold.apply(this,arguments);15.}16.};17.}18.19.20.//不传参数时，返回所有name21.functionfind0()22.{23.returnthis.names;24.}25.26.27.//传一个参数时，返回firstName匹配的name28.functionfind1(firstName)29.{30.varresult=[];31.for(vari=0;i32.{33.if(this.names[i].indexOf(firstName)===0)34.{35.result.push(this.names[i]);36.}37.}38.returnresult;39.}40.41.42.//传两个参数时，返回firstName和lastName都匹配的name43.functionfind2(firstName,lastName)44.{45.varresult=[];46.for(vari=0;i47.{48.if(this.names[i]===(firstName+""+lastName))49.{50.result.push(this.names[i]);51.}52.}53.returnresult;54.}55.56.57.varpeople={58.names:["DeanEdwards","AlexRussell","DeanTom"]59.};60.61.62.addMethod(people,"find",find0);63.addMethod(people,"find",find1);64.addMethod(people,"find",find2);65.66.67.console.log(people.find());//输出["DeanEdwards","AlexRussell","DeanTom"]68.console.log(people.find("Dean"));//输出["DeanEdwards","DeanTom"]69.console.log(people.find("Dean","Edwards"));//输出["DeanEdwards"]以上就是小编今天为大家分享的关于Web前端工程师应该知道的JavaScript的10个难点。希望本篇文章能够对正在从事Web前端学习的小伙伴们有所帮助。想要了解更多web前端相关知识记得关注北大青鸟Web培训官网最后祝愿小伙伴们工作顺利！原文链接：#/a/1190000010371988

j的四线三格写法：先从中格往下格写竖弯钩，再在上格写一点，上下格都不顶线，图片如下：1、“J”是占四线三格的两格；“中上”两格；小写“j”占三格。2、大专写字母J在四行和三个空属格中占据上述两个，写作时，应该倾斜，不要把竖直的钩子写得笔直，看起来不规则。3、形如钩的J，第10个英语和拉丁字母。它作为一个物理单元，广泛应用于惯性矩、Java编程语言等领域。注意不要粘在最上面的一行，留一点距离，然后粘在最下面的第三行。扩展资料含有字母j的单词：jump、jam、jeep、jacket、june。一、jump1、含义：n. 跳跃；跳动；上涨。v. 跳越；暴涨。2、用法jump用作及物动词时，意为“使…跳跃，使…惊起”，着重从地面、其他表面或地点跳起，可指往高处跳，也可指往低处跳，还可指跳过什么；强调的是猛然跳起或跳跃的动作，其后接名词、代词或反身代词作宾语，可用于被动结构。The athlete made a superb jump.运动运作了一个出色的跳跃。二、jam1、含义：n. 果酱。n. 堵塞；拥挤；困境。v. 塞满；挤；卡住；夹伤；干扰；猛压。2、用法jam的基本意思是“夹”“挤在中间”而四方受力，从而不能活动或脱开。常指“堵塞”“挤满”,有时也指枪、机器、零件等堵塞、移位、出现故障等而阻碍运转。I reached across the table for the jam.我伸手到桌子那端去拿果酱。
