每当我尝试构建我的 web-pack 文件或启动 web-pack 开发服务器时，我都会收到错误消息。它正在工作，但我在使用 eslint 并弄坏了一些东西。

这是尝试时的错误包 npm build

10 …

我想从数组中删除非素数，以下只是删除偶数而不是素数。

function sumPrimes(num) {
  //Produce an array containing all number of to and including num
  let numArray = [];
  for (let i = 1; i <= num; i++) {
    numArray.push(i);
  }

  //Remove non-prime numbers from the array     
  numArray.map((number) => {
    for (let i = 2; i < number; i++) {
        if(number % i === 0) {
            let index = numArray.indexOf(number);
            return numArray.splice(index, 1);       
        }
    }   
  });

 return numArray;

}

sumPrimes(10);

目前正在返回：

[1, 2, 3, 5, 7, 9]

但是，素数是1、2、3、5、7（不包括9）；
