Set is a special data structure introduced in ES6 that stores a collection of unique values. Since each value in a Set has to be unique, passing any duplicate item will be removed automatically:const numbers = [1, 2, 3, 2, 4, 5, 5, 6]; const unique = Array.from(new Set(numbers...
element(当前正在处理的元素) index(可选,当前元素的索引) array(可选,调用find方法的数组) 优势 简洁性:相比传统的for循环,find方法提供了更简洁的语法。 易读性:代码意图更加明确,易于理解。 内置优化:一旦找到符合条件的元素,就会立即停止遍历,提高了效率。
const end = array.length - nextCount; // leave room on the array for the next remaining elements for (let i = start; i < end; i += 1) { // we have already used the element at (start - 1) result[result.length - count] = array[i]; const nextStart = i + 1; // Always ...
