var arr1 = [ "574417bc79df540065d92df7", "574424e5df0eea0063adefc6", "57442329a3413100625f194f", "5744242bc4c971005d5ff04e", "574a841d1532bc006068c6c9", "574a97fe2b51e90056e423c0"];var arr2 = [ "574417bc79df540065d92df7", "57442329a3413100625f194f", "5744242bc4c971005d5ff04e", "574424e5df0eea0063adefc6", "574a841d1532bc006068c6c9"];如何快速地對比出這兩個數(shù)組中不是同時存在的元素。目測答案是："574a97fe2b51e90056e423c0"

比較初級的哈哈，

var lessArr,maxArr;if(arr1.length>arr2.length) {
    lessArr = arr2; 
    maxArr = arr1; 
}else{
    lessArr = arr1; 
    maxArr = arr2; 
}var lessStr = lessArr.join('|');var diffArr = [];for(var i=0;i<maxArr.length;i++) {    if(lessStr.indexOf(maxArr[i]) == -1) {
        diffArr.push(maxArr[i]);
    }
}console.log(diffArr.join(','));
