### pluralize
|
|
|
|
If `num` is greater than `1` returns the plural form of the given string, else return the singular form.
|
|
|
|
Check if `num` is greater than `0`. Throw an appropriate `Error` if not, return the appropriate string otherwise.
|
|
Omit the third argument, `items`, to use a default plural form same as `item` suffixed with a single `'s'`.
|
|
|
|
```js
|
|
const pluralize = (num, item, items = item + 's') =>
|
|
num <= 0
|
|
? (() => {
|
|
throw new Error(`'num' should be >= 1. Value povided was ${num}.`);
|
|
})()
|
|
: num === 1 ? item : items;
|
|
```
|
|
|
|
```js
|
|
pluralize(1, 'apple', 'apples'); // 'apple'
|
|
pluralize(3, 'apple', 'apples'); // 'apples'
|
|
pluralize(2, 'apple'); // 'apples'
|
|
pluralize(0, 'apple', 'apples'); // Gives error
|
|
pluralize(-3, 'apple', 'apples'); // Gives error
|
|
```
