写一段最短的代码，用上js所有关键字

void function() {//abcd 
  do break;while(typeof delete this);
  for(var a;;)
  if (true)  with(null)
  try{}catch(a){}finally{} else throw new 1;
 
  switch(1 in 1 instanceof 1) {
    case false:
    default:
  }
  return;
};

 改进版：

new function() {
    do break;while(typeof delete this);
    for(var a;void 0;)
        continue
    if (null)
        with(0)
    try{
        switch(1 in 1 instanceof 1) {
            case false:
            default:throw true
        }
    }catch(a){}finally{}else return  // console.log("去掉注释可以运行到这里")
};

 

此贴完美地诠释了“蛋疼”二字的含义

确实有点疼

目的就是要血染javascript？

坐等楼主提供包含所有保留关键字的

void('functionbreakdeletereturntypeofcasedoifswitchvarcatchelseinthisvoidcontinuefalseinstanceofthrowwhiledebuggerfinallynewtruewithdefaultfornulltry');

 new function(){
  try{
    for(var i in void(0)){
      break;
    }
	if(typeof null instanceof 1)
      do with(0); while(false);
	else
	  throw true
  }catch(a){
    switch(1){
	  case 1: 
	  default:
	}
  }finally{
    return delete this
  }
}
