Converts an integer to a suffixed string, adding `am` or `pm` based on its value.
|
|
|
|
Use the modulo operator (`%`) and conditional checks to transform an integer to a stringified 12-hour format with meridiem suffix.
|
|
|
|
```js
|
|
|
|
const getMeridiemSuffixOfInteger = num =>
|
|
num === 0 || num === 24
|
|
? 12 + 'am'
|
|
: num === 12
|
|
? 12 + 'pm'
|
|
: num < 12
|
|
? (num % 12) + 'am'
|
|
: (num % 12) + 'pm';
|
|
```
|
|
|
|
```js
|
|
getMeridiemSuffixOfInteger(0); // "12am"
|
|
getMeridiemSuffixOfInteger(11); // "11am"
|
|
getMeridiemSuffixOfInteger(13); // "1pm"
|
|
getMeridiemSuffixOfInteger(25); // "1pm"
|
|
``` |
