# --description--

|
|
|
Given a time string in `"HH:MM"` format (24-hour clock), return:
|
|
|
|
- `"Good morning"` for times `05:00` to `11:59`
|
|
- `"Good afternoon"` for times `12:00` to `17:59`
|
|
- `"Good evening"` for times `18:00` to `21:59`
|
|
- `"Good night"` for times `22:00` to `04:59`
|
|
|
|
# --hints--
|
|
|
|
`getGreeting("06:30")` should return `"Good morning"`.
|
|
|
|
```js
|
|
assert.equal(getGreeting("06:30"), "Good morning");
|
|
```
|
|
|
|
`getGreeting("12:00")` should return `"Good afternoon"`.
|
|
|
|
```js
|
|
assert.equal(getGreeting("12:00"), "Good afternoon");
|
|
```
|
|
|
|
`getGreeting("21:59")` should return `"Good evening"`.
|
|
|
|
```js
|
|
assert.equal(getGreeting("21:59"), "Good evening");
|
|
```
|
|
|
|
`getGreeting("00:01")` should return `"Good night"`.
|
|
|
|
```js
|
|
assert.equal(getGreeting("00:01"), "Good night");
|
|
```
|
|
|
|
`getGreeting("11:30")` should return `"Good morning"`.
|
|
|
|
```js
|
|
assert.equal(getGreeting("11:30"), "Good morning");
|
