Copy of the object, an array of

var deepCopy = function(obj) {
　　if (typeof obj !== 'object') return;
　　var newObj = obj instanceof Array ? [] : {};
　　for (var key in obj) {
　　　　if (obj.hasOwnProperty(key)) {
　　　　　　newObj[key] = typeof obj[key] === 'object' ? deepCopy(obj[key]) : obj[key];
　　　　}
　　}
　　return newObj;
}

 

Disrupt the array, and lists the array after each upset

This method is particularly stupid, there is no better we all make a suggestion!

function upsetArr (arr) {
  var obj= {};
  for (let i = 0; i < arr.length - 1; i++) {
        for (let j = i + 1; j < arr.length; j++) {
            var tempArr = deepCopy(arr);
            var temp = tempArr[j];
            tempArr[j] = tempArr[i];
            tempArr[i] = temp;
            obj[i+''+j] = tempArr;
        }    
    }
    return obj;
}
var arrObj = upsetArr([1,2,3])
console.log(arrObj)

Print out the results:
