This article mainly introduces the method of random sorting of js arrays, which has certain reference value. Now I share it with everyone. Friends in need can refer to it.
Method 1:
function getRandomInt(min, max) { return Math.floor(Math.random() * (max - min + 1) + min)
}
function shuffle(arr) {
let _arr = arr.slice() for (let i = 0; i < _arr.length; i++) {
let j = getRandomInt(0, i)
let t = _arr[i]
_arr[i] = _arr[j]
_arr[j] = t
} return _arr
}
console.log(shuffle([11,22,33,4,5,6]))Method 2:
arr.sort(function(){
Math.random()>0.5?1:-1

How to get the length of an array in js
Jun 20, 2023 pm 05:33 PM
Getting the length of an array in JS is very simple. Each array has a length property, which returns the maximum length of the array, that is, its value is equal to the maximum subscript value plus 1. Since numeric subscripts must be less than 2^32-1, the maximum value of the length attribute is equal to 2^32-1. The following code defines an empty array, and then assigns a value to the element with the index equal to 100, then the length property returns 101. Therefore, the length attribute cannot reflect the actual number of array elements.

By default, the sort() method sorts strings according to their Unicode code point values. This means that it is used primarily for sorting strings and numbers, rather than for sorting objects or other complex data types.
