从数组Javascript中删除特定元素

const array = [1, 2, "特定元素", 3, 4, "特定元素"];
const filteredArray = array.filter(item => item !== "特定元素");
console.log(filteredArray);

const array = [1, 2, "特定元素", 3, 4, "特定元素"];
const index = array.indexOf("特定元素");
if (index > -1) {
  array.splice(index, 1);
}
console.log(array);

const array = [1, 2, "特定元素", 3, 4, "特定元素"];
const filteredArray = array.reduce((acc, item) => {
  if (item !== "特定元素") {
    acc.push(item);
  }
  return acc;
}, []);
console.log(filteredArray);

const array = [1, 2, "特定元素", 3, 4, "特定元素"];
for (let i = array.length - 1; i >= 0; i--) {
  if (array[i] === "特定元素") {
    array.splice(i, 1);
  }
}
console.log(array);
