# --description--
Given an integer representing the number of years a couple has been married, return their most recent anniversary milestone according to this chart:
| Years Married | Milestone |
| ------------- | ------------ |
| 1 | `"Paper"` |
| 5 | `"Wood"` |
| 10 | `"Tin"` |
| 25 | `"Silver"` |
| 40 | `"Ruby"` |
| 50 | `"Gold"` |
| 60 | `"Diamond"` |
| 70 | `"Platinum"` |
- If they haven't reached the first milestone, return `"Newlyweds"`.
# --hints--
`getMilestone(0)` should return `"Newlyweds"`.
```js
assert.equal(getMilestone(0), "Newlyweds");
```
`getMilestone(1)` should return `"Paper"`.
```js
assert.equal(getMilestone(1), "Paper");
```
`getMilestone(8)` should return `"Wood"`.
```js
assert.equal(getMilestone(8), "Wood");
```
`getMilestone(10)` should return `"Tin"`.
```js
assert.equal(getMilestone(10), "Tin");
```
`getMilestone(26)` should return `"Silver"`.
```js
assert.equal(getMilestone(26), "Silver");
```
`getMilestone(45)` should return `"Ruby"`.
```js
assert.equal(getMilestone(45), "Ruby");
```
`getMilestone(50)` should return `"Gold"`.
```js
assert.equal(getMilestone(50), "Gold");
```
`getMilestone(64)` should return `"Diamond"`.
```js
assert.equal(getMilestone(64), "Diamond");
```
`getMilestone(71)` should return `"Platinum"`.
```js
assert.equal(getMilestone(71), "Platinum");
```
