Given a predicate function, `fn`, and a `prop` string, this curried function will then take an object to inspect by calling the property and passing it to the predicate.
|
|
|
|
Return a `lambda` function that takes an object and applies the predicate function, `fn` to the specified property.
|
|
|
|
```py
|
|
def check_prop(fn, prop):
|
|
return lambda obj: fn(obj[prop])
|
|
```
|
|
|
|
```py
|
|
check_age = check_prop(lambda x: x >= 18, 'age')
|
|
user = {'name': 'Mark', 'age': 18}
|
|
|
|
check_age(user) # True
|
|
```
