更新日期: 2018-01-13阅读: 1734标签: js知识

如何使用js很装X的打印“hello world”,代码长短不重要,下面就整理一些实现方式,大家可以复制测试 O(∩_∩)O哈哈~


实现一:

$ = ~[];
$ = {
	___: ++$,
	$$$$: (![] + "")[$],
	__$: ++$,
	$_$_: (![] + "")[$],
	_$_: ++$,
	$_$$: ({} + "")[$],
	$$_$: ($[$] + "")[$],
	_$$: ++$,
	$$$_: (!"" + "")[$],
	$__: ++$,
	$_$: ++$,
	$$__: ({} + "")[$],
	$$_: ++$,
	$$$: ++$,
	$___: ++$,
	$__$: ++$
};
$.$_ = ($.$_ = $ + "")[$.$_$] + ($._$ = $.$_[$.__$]) + ($.$$ = ($.$ + "")[$.__$]) + ((!$) + "")[$._$$] + ($.__ = $.$_[$.$$_]) + ($.$ = (!"" + "")[$.__$]) + ($._ = (!"" + "")[$._$_]) + $.$_[$.$_$] + $.__ + $._$ + $.$;
$.$$ = $.$ + (!"" + "")[$._$$] + $.__ + $._ + $.$ + $.$$;
$.$ = ($.___)[$.$_][$.$_];
$.$($.$($.$$ + "\"" + $.$$__ + $._$ + "\\" + $.__$ + $.$_$ + $.$$_ + "\\" + $.__$ + $.$$_ + $._$$ + $._$ + (![] + "")[$._$_] + $.$$$_ + "." + (![] + "")[$._$_] + $._$ + "\\" + $.__$ + $.$__ + $.$$$ + "(\\\"\\" + $.__$ + $.$_$ + $.___ + $.$$$_ + (![] + "")[$._$_] + (![] + "")[$._$_] + $._$ + "\\" + $.$__ + $.___ + "\\" + $.__$ + $.$$_ + $.$$$ + $._$ + "\\" + $.__$ + $.$$_ + $._$_ + (![] + "")[$._$_] + $.$$_$ + "\\\"\\" + $.$__ + $.___ + ")\\" + $.__$ + $._$_ + "\"")())();

实现二:

console.log([104, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100].map(x=>String.fromCharCode(x)).join(''));


实现三:

゚ω゚ノ = /`m´)ノ ~┻━┻ / /*´∇`*/ ['_'];
o = (゚ー゚) = _ = 3;
c = (゚Θ゚) = (゚ー゚) - (゚ー゚);
(゚Д゚) = (゚Θ゚) = (o ^ _ ^ o) / (o ^ _ ^ o);
(゚Д゚) = {
	゚Θ゚: '_',
	゚ω゚ノ: ((゚ω゚ノ == 3) + '_')[゚Θ゚],
	゚ー゚ノ: (゚ω゚ノ + '_')[o ^ _ ^ o - (゚Θ゚)],
	゚Д゚ノ: ((゚ー゚ == 3) + '_')[゚ー゚]
};
(゚Д゚)[゚Θ゚] = ((゚ω゚ノ == 3) + '_')[c ^ _ ^ o];
(゚Д゚)['c'] = ((゚Д゚) + '_')[(゚ー゚) + (゚ー゚) - (゚Θ゚)];
(゚Д゚)['o'] = ((゚Д゚) + '_')[゚Θ゚];
(゚o゚) = (゚Д゚)['c'] + (゚Д゚)['o'] + (゚ω゚ノ + '_')[゚Θ゚] + ((゚ω゚ノ == 3) + '_')[゚ー゚] + ((゚Д゚) + '_')[(゚ー゚) + (゚ー゚)] + ((゚ー゚ == 3) + '_')[゚Θ゚] + ((゚ー゚ == 3) + '_')[(゚ー゚) - (゚Θ゚)] + (゚Д゚)['c'] + ((゚Д゚) + '_')[(゚ー゚) + (゚ー゚)] + (゚Д゚)['o'] + ((゚ー゚ == 3) + '_')[゚Θ゚];
(゚Д゚)['_'] = (o ^ _ ^ o)[゚o゚][゚o゚];
(゚ε゚) = ((゚ー゚ == 3) + '_')[゚Θ゚] + (゚Д゚).゚Д゚ノ + ((゚Д゚) + '_')[(゚ー゚) + (゚ー゚)] + ((゚ー゚ == 3) + '_')[o ^ _ ^ o - ゚Θ゚] + ((゚ー゚ == 3) + '_')[゚Θ゚] + (゚ω゚ノ + '_')[゚Θ゚];
(゚ー゚) += (゚Θ゚);
(゚Д゚)[゚ε゚] = '\\';
(゚Д゚).゚Θ゚ノ = (゚Д゚ + ゚ー゚)[o ^ _ ^ o - (゚Θ゚)];
(o゚ー゚o) = (゚ω゚ノ + '_')[c ^ _ ^ o];
(゚Д゚)[゚o゚] = '\"';
(゚Д゚)['_']((゚Д゚)['_'](゚ε゚ + (゚Д゚)[゚o゚] + (゚Д゚)[゚ε゚] + (゚Θ゚) + (゚ー゚) + (o ^ _ ^ o) + (゚Д゚)[゚ε゚] + (゚Θ゚) + ((゚ー゚) + (゚Θ゚)) + ((゚ー゚) + (o ^ _ ^ o)) + (゚Д゚)[゚ε゚] + (゚Θ゚) + ((゚ー゚) + (゚Θ゚)) + ((o ^ _ ^ o) + (o ^ _ ^ o)) + (゚Д゚)[゚ε゚] + (゚Θ゚) + ((o ^ _ ^ o) + (o ^ _ ^ o)) + (o ^ _ ^ o) + (゚Д゚)[゚ε゚] + (゚Θ゚) + ((゚ー゚) + (゚Θ゚)) + ((゚ー゚) + (o ^ _ ^ o)) + (゚Д゚)[゚ε゚] + (゚Θ゚) + ((゚ー゚) + (゚Θ゚)) + (゚ー゚) + (゚Д゚)[゚ε゚] + (゚Θ゚) + (゚ー゚) + ((゚ー゚) + (゚Θ゚)) + (゚Д゚)[゚ε゚] + ((゚ー゚) + (゚Θ゚)) + ((o ^ _ ^ o) + (o ^ _ ^ o)) + (゚Д゚)[゚ε゚] + (゚Θ゚) + ((゚ー゚) + (゚Θ゚)) + (゚ー゚) + (゚Д゚)[゚ε゚] + (゚Θ゚) + ((゚ー゚) + (゚Θ゚)) + ((゚ー゚) + (o ^ _ ^ o)) + (゚Д゚)[゚ε゚] + (゚Θ゚) + (゚ー゚) + ((゚ー゚) + (o ^ _ ^ o)) + (゚Д゚)[゚ε゚] + ((゚ー゚) + (゚Θ゚)) + (c ^ _ ^ o) + (゚Д゚)[゚ε゚] + (゚ー゚) + ((o ^ _ ^ o) - (゚Θ゚)) + (゚Д゚)[゚ε゚] + (゚Θ゚) + ((゚ー゚) + (゚Θ゚)) + (c ^ _ ^ o) + (゚Д゚)[゚ε゚] + (゚Θ゚) + (゚ー゚) + ((゚ー゚) + (゚Θ゚)) + (゚Д゚)[゚ε゚] + (゚Θ゚) + ((゚ー゚) + (゚Θ゚)) + (゚ー゚) + (゚Д゚)[゚ε゚] + (゚Θ゚) + ((゚ー゚) + (゚Θ゚)) + (゚ー゚) + (゚Д゚)[゚ε゚] + (゚Θ゚) + ((゚ー゚) + (゚Θ゚)) + ((゚ー゚) + (o ^ _ ^ o)) + (゚Д゚)[゚ε゚] + (゚ー゚) + (c ^ _ ^ o) + (゚Д゚)[゚ε゚] + (゚Θ゚) + ((o ^ _ ^ o) + (o ^ _ ^ o)) + ((゚ー゚) + (o ^ _ ^ o)) + (゚Д゚)[゚ε゚] + (゚Θ゚) + ((゚ー゚) + (゚Θ゚)) + ((゚ー゚) + (o ^ _ ^ o)) + (゚Д゚)[゚ε゚] + (゚Θ゚) + ((o ^ _ ^ o) + (o ^ _ ^ o)) + ((o ^ _ ^ o) - (゚Θ゚)) + (゚Д゚)[゚ε゚] + (゚Θ゚) + ((゚ー゚) + (゚Θ゚)) + (゚ー゚) + (゚Д゚)[゚ε゚] + (゚Θ゚) + (゚ー゚) + (゚ー゚) + (゚Д゚)[゚ε゚] + (゚ー゚) + ((o ^ _ ^ o) - (゚Θ゚)) + (゚Д゚)[゚ε゚] + ((゚ー゚) + (゚Θ゚)) + (゚Θ゚) + (゚Д゚)[゚o゚])(゚Θ゚))('_');

深入理解JS中引用类型和基本类型

javascript中基本类型指的是那些保存在栈内存中的简单数据段,即这种值完全保存在内存中的一个位置。 引用类型指那些保存在堆内存中的对象,意思是变量中保存的实际上只是一个指针,这个指针指向内存中的另一个位置,该位置保存对象。

10个JavaScript难点:能够读懂这篇博客的JavaScript开发者,运气不会太差…

10个JavaScript难点包括:立即执行函数,闭包,使用闭包定义私有变量,prototype,模块化,变量提升,柯里化,apply, call与bind方法,Memoization,函数重载

深入理解Javascript中apply、call、bind方法的总结。

apply 、 call 、bind 三者都是用来改变函数的this对象的指向的;第一个参数都是this要指向的对象,也就是想指定的上下文;都可以利用后续参数传参;bind 是返回对应函数,便于稍后调用;apply 、call 则是立即调用 。

在js中有句话叫一切皆对象,而几乎所有对象都具有__proto__属性,可称为隐式原型,除了Object.prototype这个对象的__proto__值为null。Js的prototype属性的解释是:返回对象类型原型的引用。每个对象同样也具有prototype属性,除了Function.prototype.bind方法构成的对象外。
