Create the following functions, which each take an array as the first argument, and a function as the second argument.
|
|
|
|
|
|
|
|
|
|
- `filter`: that works like the `[].filter` method.
|
|
|
|
|
|
|
|
|
|
- `reject`: that works like the `reject` function from lodash.
|
|
|
|
|
|
|
|
|
|
- `partition`: that works like the `partition` function from lodash.
