1.5.1.不可变数据结构 JavaScript 一共有 6 种原始类型(包括 ES6 新添加的 Symbol 类型),它们分别是 Boolean,Null,Undefined,Number,String 和 Symbol。 除了这些原始类型,其他的类型都是 Object,而 Object 都是可变的。 1.5.2.惰性求值 惰性(lazy)指求值的过程并不会立刻发生。 比如一些数学题,我们可能一开始...
We are required to write a JavaScript function that takes in two numbers, say, a and b and returns the total number of prime numbers between a and b (including a and b, if they are prime). For example − If a = 2, and b = 21, the prime numbers between them are 2, 3, 5,...
let sum = 0; while (newNum>0) { last = newNum%10; sum = sum + (last*last*last*last); newNum = parseInt(newNum/10); } if (num===sum) { console.log("number is ARMSTRONG number"); }else{ console.log("not armstrong number") } STDIN Output: number is ARMSTRONG number ...
