# Flatten Array
|
|
|
|
Take a nested list and return a single flattened list with all values except nil/null.
|
|
|
|
The challenge is to write a function that accepts an arbitrarily-deep nested list-like structure and returns a flattened structure without any nil/null values.
|
|
|
|
For Example
|
|
|
|
input: [1,[2,3,null,4],[null],5]
|
|
|
|
output: [1,2,3,4,5]
|
