A number is prime if it has only two distinct divisors: 1 and itself. For example, 3 is a prime number because it has only two distinct divisors: 1 and 3. Return "Prime" if num is prime; otherwise, return "Not Prime". 1 2 3 function checkPrime(num) { } Check Code Share ...
For example, 371 is an Armstrong number since 3 ^ 3 + 7 ^ 3 + 1 ^ 3 = 27 + 343 + 1 = 371. Return "Armstrong" if num is an Armstrong Number. Otherwise, return "Not Armstrong". 1 2 3 function checkArmstrongNumber(num) { } Check Code Share on: Did you find this articl...

// So technically to determine if a number is prime you only need to // check numbers up to the square root. However this function only runs // once and we're only computing the first 64 primes (up to 311), so on // any modern CPU this whole function runs in a couple millisecond...

这些应该是字符串,比如“number”和“boolean”,这是typeof运算符返回的。你还可以指定第三个参数:一个包含[key,value]数组的数组(或任何可迭代对象),指定地图中的初始条目。如果指定了任何初始条目,构造函数首先验证它们的类型是否正确。接下来,构造函数使用super关键字调用超类构造函数,就像它是一个函数名一样。
