如何在JavaScript中使用过滤器函数实现Continue语句

Question

As I'm new to JS i implemented filter function on an array. I want to skip some iterations . How can I implement continue statement etc in filter function

Answer 1

Filter takes a callback function that returns a boolean, it doesn't skip iterations. If you would like to exclude an element from your result, your callback function should return false.

Ie if I wanted to filter all odd numbers from an array:

const numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9];
const evenNumbers = numbers.filter(number => number % 2 === 0); // [2, 4, 6, 8]
