Takes a variadic function and returns a closure that accepts an array of arguments to map to the inputs of the function.
|
|
|
|
Use closures and the spread operator (`...`) to map the array of arguments to the inputs of the function.
|
|
|
|
```js
|
|
const spreadOver = fn => argsArr => fn(...argsArr);
|
|
```
|
|
|
|
```js
|
|
const arrayMax = spreadOver(Math.max);
|
|
arrayMax([1, 2, 3]); // 3
|
|
```
