const _factorial = number => { return number < 2 ? 1 : number * _factorial(number - 1) } 1. 2. 3. 所有的递归函数都有相同的模式。它们由创建一个调用自身的递归部分和一个不调用自身的基本部分组成。任何时候一个函数调用它自身都会创建一个新的执行上下文并推入执行栈顶直。这种情况会
If you need to support truly obsolete JavaScript engines that do not support Object.defineProperty, it is best not to polyfill Array.prototype methods at all, as you cannot make them non-enumerable.ExamplesFind the index of a prime number in an array...
Javascript In this problem, we are given an array of integers, which may contain both negative and positive numbers. We have to find the average of all the negative numbers in the array. In this article, we are going to learn how we can find the average of all negative numbers in...
