### Truncate a String
|
|
|
|
Determine if the string's `length` is greater than `num`.
|
|
Return the string truncated to the desired length, with `...` appended to the end or the original string.
|
|
|
|
```js
|
|
const truncateString = (str, num) =>
|
|
str.length > num ? str.slice(0, num > 3 ? num - 3 : num) + '...' : str;
|
|
// truncate('boomerang', 7) -> 'boom...'
|
|
```
