最后使用filter()方法将这些不同的元素保存在newArr中。 functiondiff(arr1, arr2) {varnewArr =[];vararr3=arr1.concat(arr2);//将arr1和arr2合并为arr3functionisContain(value){//找出arr3中不存在于arr1和arr2中的元素returnarr1.indexOf(value)==-1||arr2.indexOf(value)==-1; } newArr=ar...
function diff(oldData, newData) { // id 只在 newData 中存在且不在 oldData 中存在的即为 add const add = newData.filter(e => !oldData.find(c => c.id === e.id)); // id 只在 oldData 中存在且不在 newData 中存在的即为 dele const dele = oldData.filter(e => !newData.find...

JsDiff.diffJson(oldObj, newObj[, options])- diffs two JSON objects, comparing the fields defined on each. The order of fields, etc does not matter in this comparison. Returns a list of change objects (See below). JsDiff.diffArrays(oldArr, newArr[, options])- diffs two arrays, comparin...
17 console.log(sameArray); // ['one', 'two', 'three'] 18 console.log(diffArray); // ['four', 'five'] 19 20 function getDifferentArrays(array1, array2) { 21 return array1.concat(array2).filter(function (v, i, array) { ...
To calculate the number of days between two dates, We first find the absolute value between the two dates, then divide it by 86400000 (equal to the number of milliseconds in a day), and finally round the result and return it. const daysDiff = (date, date2) => Math.ceil(Math.abs(da...
// bad - git diff without trailing comma const hero = { firstName: 'Florence', - lastName: 'Nightingale' + lastName: 'Nightingale', + inventorOf: ['coxcomb chart', 'modern nursing'] }; // good - git diff with trailing comma const hero = { firstName: 'Florence', lastName: 'Nigh...
In the curry method, I capture the arguments for the first function call, and those from the second, concatenate the two, and then use the Function apply method to return a function with the combined set of arguments. The code then uses the curry method to create a new function, diff...
reduce((acc, subArr) => { const diff = subArr[1] - subArr[0]; return acc + diff; }, 0); console.log("The sum of the differences of subarrays: "); console.log(sum); Example using a for loop Open Compiler // define array ...
2.Diff Two Arrays 比较两个数组,然后返回一个新数组,该数组的元素为两个给定数组中所有独有的数组元素。换言之,返回两个数组的差异。 答: function diff(arr1, arr2) { var newArr1 = arr1.filter(function(item,index,array){//item是arr1里面的元素 return ...
