Then, you need to create anifblock to check if the array lengths are equal. Only when the length properties are equal will you check on the array values: letarrOne=[1,5,6];letarrTwo=[1,6,5];letresult=false;if(arrOne.length===arrTwo.length){for(leti=0;i<arrOne.length;i++){/...
Declare a function, which is used to compare two arrays and find common elements. first of all, Declare an empty array name arr. iterate through all the elements in one of the arrays. Then, for each element in this array, iterate through all the elements of the other array. If the ele...
Another technique to compare two arrays is to first cast them to the string type and then compare them.JSONis used to transfer data from/to a web server, but we can use its method here. We can do this is usingJSON.stringify()that converts anArrayto astring. As now both thea1anda2ar...
在第五行后加入 然后在代码中需要替换的地方将this和array替换成排序后的新数组 再次答应即可得到true
5 Array.prototype.equals = function (array) { 6 // if the other array is a falsy value, return 7 if (!array) 8 return false; 9 10 // compare lengths - can save a lot of time 11 if (this.length != array.length) 12 return false; ...

Here's how you can use Lodash'sisEqual()function to compare arrays: const_=require('lodash');functionarraysAreEqualUsingLodash(arr1,arr2){return_.isEqual(arr1,arr2);}console.log(arraysAreEqualUsingLodash(array1,array2));// true
A short article to learn how to compare two arrays to check if they are equal in vanilla JavaScript.
constfruits=newArray('Apple','Banana');console.log(fruits.length); 数组文字表示法 使用数组文本声明,我们指定数组将具有的值。如果我们不声明任何值,数组将为空。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 // 'fruits' array created using array literal notation.constfruits=['Apple','Banana'...
Javascript 中 Array的 sort()和 compare()方法 Javascript 中 Array的 sort()方法其实是把要排序的内容转化为string(调用 toString()), 然后按照字符串的第一位 ascii 码先后顺序进行比较,不是数字。 我们看看官方是怎么说的: arrayobj.sort(sortfunction)...
