尝试删除/移除数组中的特定字符串时如何使用 .splice()？

Question

I've created a successful way of removing the strings in an array, but is there a way to remove specific parts in an array using .splice()

const arr = [1000, 2000, "numbers", 5000, 6000, "integers"];

getInt = (arr) => {
  return arr.map((i)=> {if (/^\d+$/.test(i))
   return i;
  });
}
getInt(arr);

console.log(getInt(arr));

Answer 1

const arr = [1000, 2000, "numbers", 5000, 6000, "integers"];

console.log(arr.filter(item =>  Number.isInteger(item)))

You can use filter method to filter out the integers, give it a try mate.

Answer 2

let arr = [1000, 2000, "number", 5000, 6000, "integers"];
getInt = (arr) => {
  for (i=0; i<arr.length; i++) {
    if (Object.prototype.toString.call(arr[i]) === "[object String]") {
      arr.splice(i, 1)
    }
  };
}
getInt(arr)
console.log(arr) // [1000, 2000, 5000, 6000]
