如何在数组中找到最大的一组数字并分别用javascript返回? [英] How to find the largest group of numbers in an array and return them separately in javascript?

问题描述

如何制作仅返回大于输入数字的数字的函数? 我的代码在这里不起作用，我也不知道为什么.

How can I make a function that returns only the numbers greater than the number that I entered? My code here isn't working, and I don't know why.

var arr = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
var num = Number(prompt('number'));

function findBiggestNumbers(num) {
   for (var i = 0; i < arr.length; i++) {
      if (arr[i] > num) {
         num = arr[i];
      }
   }
   return num;
// }
console.log(findBiggestNumbers(num));

推荐答案

要使用数组，您可以使用filter函数，它会返回带有一定条件的数组子集.因此，您可以轻松做到:

To work with arrays you could use the filter function, it returns a subset of the array with some condition. So, you can simpley do:

var num = 5; //using 5 as an example

a = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];

var b = a.filter(number => number > num);

您可以将其放入函数中.

You can put this into an function.
