Transferablesサポートチェック

// Transferablesの方がBlobURLよりサポートが遅いし、BlobURLsを使わないと外部JSなしでworkerを作れないのでこうしている

monjudoh / classbox.js
Created September 11, 2012 05:18
classboxよく分かってないんだけどJavaScriptでやるとこんな感じ?__proto__のsetを使っているので標準準拠で実装できません。
var classbox = (function () {
var proto = Array.prototype;
var proto2 = Object.create(Object.getPrototypeOf(proto));
Object.getOwnPropertyNames(proto).forEach(function(propName){
var desc = Object.getOwnPropertyDescriptor(proto,propName);
Object.defineProperty(proto2,propName,desc);
});
proto2.first = function first() {
return this[0];

JSでFizzBuzz。剰余と一切の条件分岐を無くしたよ。さらに、元々ループと再帰はなかったけど、反復メソッドも(見かけ上)なくしたよ。
fizzArray = [];
buzzArray = [];
new Array(101).join('a').replace(/a/g,function(n,i){
fizzArray = fizzArray.concat(['','','Fizz']);
buzzArray = buzzArray.concat(['','','','','Buzz']);
var result = (fizzArray[i]+buzzArray[i]).replace(/^$/,i + 1);
return result + '\n';
});

FizzBuzzを久々に素直に書いたら長くなった
Array.apply(null,new Array(101))
.map(function(n,i){ return '';})
.map(function(n,i){ return n+(i % 3 ? '' : 'Fizz');})
.map(function(n,i){ return n+(i % 5 ? '' : 'Buzz');})
.map(function(n,i){ return n ? n : i;})
.slice(1,101)

IE(主に6,7)で「操作は中断されました」エラーが出るヶ所でstackTraceをalertで出す。これに依存→ https://github.com/emwendelin/javascript-stacktrace
(function(){
var domManip = jQuery.fn.domManip;
jQuery.fn.domManip = function(){
if(!jQuery.isReady && !!this.closest('body').size() ) {
var msg = printStackTrace().join('\n');
alert(msg);
throw new Error();
}
return domManip.apply(this,arguments);
}
