412 Fizz Buzz.js

/**
 * Write a program that outputs the string representation of numbers
 * from 1 to n.
 * But for multiples of three it should output “Fizz” instead of the
 * number and for the multiples of five output “Buzz”. For numbers
 * which are multiples of both three and five output “FizzBuzz”.
 * 写一个程序，输出从 1 到 n 数字的字符串表示。
 * 1. 如果 n 是3的倍数，输出“Fizz”；
 * 2. 如果 n 是5的倍数，输出“Buzz”；
 * 3.如果 n 同时是3和5的倍数，输出 “FizzBuzz”。
