fizzBuzz array issues

问题

I am doing a fizzbuzz challenge in JavaScript where I create a function that accepts a number and returns an array that is the length of the number. When there is a multiple of 3 it will say "fizz" and when there is a multiple of 5 it will say "buzz," and then lastly if it is a multiple of 3 and 5 it will say "fizzBuzz."

  1. [0, 1, 'fizz', 3, 'buzz', 'fizz', 6, 7, 'fizz', 'buzz', 10, 'fizz', 12, 13, 'fizzBuzz']

I do it this way because the array starts at 0. But when I try to do this it ends up getting an output like this:

  1. ['fizzBuzz', 1, 'fizz', 3, 'buzz', 'fizz', 6, 7, 'fizz', 'buzz', 10, 'fizz', 12, 13, 'fizzBuzz']

Code:

  1. let someArray = []
  3. const fizzBuzz = () => {
  4.     for (let i = 0; i <= 15; i++) {
  5.         if (i % 3 === 0) {
  6.             someArray.pop()
  7.             someArray.push("fizz")
  8.         } if (i % 5 === 0) {
  9.             someArray.pop()
  10.             someArray.push("buzz")
  11.         }  if (i % 15 === 0) {
  12.             someArray.pop()
  13.             someArray.push("fizzBuzz")
  14.         }   else {
  15.             someArray.push(i)
  16.         }
  17.     }
  18. }
  19. fizzBuzz()

I have also seen where you can do it this way:

  1. let someArray = []
  3. const fizzBuzz = () => {
  4.     for (let i = 0; i <= 15; i++) {
  5.         if (i % 15 === 0) {
  6.             someArray.push("fizzbuzz")
  7.         } else if (i % 3 === 0) {
  8.             someArray.push("fizz")
  9.         } else if (i % 5 === 0) {
  10.             someArray.push("buzz")
  11.         }  else {
  12.             someArray.push(i)
  13.         }
  14.     }
  15. }
  16. fizzBuzz()

This gets it right on 3 and 5, but still adds the "fizzBuzz" to the beginning of the array:

  1. ['fizzbuzz', 1, 2, 'fizz', 4, 'buzz', 'fizz', 7, 8, 'fizz', 'buzz', 11, 'fizz', 13, 14, 'fizzbuzz']

Is there something that I am doing wrong? and which way would be the correct way to do this? Or if there is a better way to do this?

得分: 1

你可以选择从1开始循环，或者在if语句中处理零的条件...

  1. const fizzBuzz = () => {
  2.     for (let i = 0; i <= 15; i++) {
  3.         if (i === 0) {
  4.             someArray.push(i)
  5.         } else if (i % 15 === 0) {
  6.             someArray.push("fizzbuzz")
  7.         } else if (i % 3 === 0) {
  8.             someArray.push("fizz")
  9.         } else if (i % 5 === 0) {
  10.             someArray.push("buzz")
  11.         }  else {
  12.             someArray.push(i)
  13.         }
  14.     }
  15. }

You can either start the loop at 1 or handle the condition for zero in the if statements...

  1. const fizzBuzz = () =&gt; {
  2.         for (let i = 0; i &lt;= 15; i++) {
  3.             if (i === 0) {
  4.               someArray.push(i)
  5.             } else if (i % 15 === 0) {
  6.                 someArray.push(&quot;fizzbuzz&quot;)
  7.             } else if (i % 3 === 0) {
  8.                 someArray.push(&quot;fizz&quot;)
  9.             } else if (i % 5 === 0) {
  10.                 someArray.push(&quot;buzz&quot;)
  11.             }  else {
  12.                 someArray.push(i)
  13.             }
  14.         }
  15.     }
