The factorial of a non-negative integer n is the product of all positive integers less than or equal to n. For example, the factorial of 3 is 3 * 2 * 1 = 6. Return the factorial of the input number num. 1 2 3 function calculateFactorial(num) { } Check Code Share on: Did...
const square = function (number) { return number * number; }; console.log(square(4)); // 16 然而,也可以为函数表达式提供名称,并且可以用于在函数内部代指其本身,或者在调试器堆栈跟踪中识别该函数: jsCopy to Clipboard const factorial = function fac(n) { return n < 2 ? 1 : n * fac(n...
//maximum number Math.max(...nums); //returns 99 1. 2. 3. 4. 5. 7、检查性能 如果你想检查一段代码运行和执行需要多长时间,你可以像我们在下面的例子中那样使用 performance.now() 方法: AI检测代码解析 var start = performance.now(); //Your piece of code starts here for(let i = 0; i...
function factorial(n) { // A function to compute factorials let product = 1; // Start with a product of 1 while(n > 1) { // Repeat statements in {} while expr in () is true product *= n; // Shortcut for product = product * n; ...
可通过new String(),new Number(),new Boolean()来显式创建包装对象(即原始值转换成他们各自的包装对象)。(当不用new运算符调用这些函数时,它们会作为类型转换函数,看显式类型转换部分) 例子1: let num1 = 1; // 数字 let num2 = new Number(num1); // 数字对象 ...
a = 1; window.a // 1 该种方式在 ECMAScript 5 的严格模式(strict)下是不被允许的。 数据类型 下面是ECMAScript5 的数据类型: 对于数据类型的检测,JavaScript中也提供了一个内置的操作符 -- typeof,通过 typeof 我们可以准确的获得"string"、"number"、"boolean"、"undefined"等基本数据类型,但是需要注...
A factorial of a number is the product of that integer and all the positive integers that are lesser than or equal to it. It has to be a positive integer - otherwise, the logic extends to negative infinity. In other words - calculating a factorial means multiplying all whole numbers betwee...
