Returns the product of two or more numbers/arrays.
|
|
|
|
- Use `Array.prototype.reduce()` to multiply each value with an accumulator, initialized with a value of `1`.
|
|
|
|
```js
|
|
const prod = (...arr) => [...arr].reduce((acc, val) => acc * val, 1);
|
|
```
|
|
|
|
```js
|
|
prod(1, 2, 3, 4); // 24
|
|
prod(...[1, 2, 3, 4]); // 24
|
|
```
