letscores = [9,80,10,20,5,70];// sort numbers in ascending orderscores.sort((a, b) =>a - b); console.log(scores); 输出: [5,9,10,20,70,80] 要以降序对数字数组进行排序,您只需要反转比较函数中的逻辑,如...
function ascendingComp(a, b){ return (a-b); } 把比较器函数传入sort()方法: numbers.sort(ascendingComp); // retruns [1, 5, 9, 10, 13, 23, 37, 56, 100] /* 也可以使用行内函数: numbers.sort(function(a, b) { return (a-b); }); 或者使用箭头函数的写法: numbers.sort((a, b)...
如果compare(a,b) 大于零,则 sort() 方法将 b 排序为比 a 低的索引,即 b 将排在最前面。 如果compare(a,b) 返回零,则 sort() 方法认为 a 等于 b 并保持它们的位置不变。 要解决排序数字的问题,您可以使用以下语法: let numbers = [0, 1 , 2, 3, 10, 20, 30 ]; numbers.sort( function( ...
// Sort array of numbers in ascending order let numbers = [ 100, 14, 25, 5, 101, 33 ]; numbers.sort(function(a,b){ if(a < b) { return -1; } else if(a > b) { return 1; } else { return 0; } }); console.log(numbers); // [ 5, 14, 25, 33, 100, 101 ] 使用箭...
如果需要对包含数字的 Set 进行排序,则必须将函数传递给Array.sort()方法。 // ✅ Sort a Set containing Numbersconstset1 =newSet([300,100,700]);// 👇️ sorts numbers in Ascending orderconstsortedArray =Array.from(set1).sort((a, b) =>a - b);console.log(sortedArray);// 👉️ ...
Using a Sort Function Sort numbers in ascending order: // Create an Array constpoints = [40,100,1,5,25,10]; // Sort the Array points.sort(function(a, b){returna-b}); Try it Yourself » Sort numbers in descending order:
TL;DR —Sort an array of numbers in ascending order using: myArray.sort((a, b) => a - b); Arraysin JavaScript are data structures consisting of a collection of data items. Because Javascript is not a typed language, Javascript arrays can contain different types of elements -strings,numbe...
