allow child to be undefined or null #40

There was a problem hiding this comment.
I think there is one issue with the implementation, if the value of child is 0 (number), the will be filtered out.
I'm thinking of the implementation like:
children.map(c => c ?? []).flat(Infinity).forEach(...)Thanks so much for your contribution! I will do the merging this or next Friday, depending on my availability (currently only on Fridays I have convenient available personal time to work on this project).

Good catch, the filtering should be placed after the flattening, shoudn't it ? |

After For example [undefined, 1].map(c => c ?? []) // [[], 1][[], 1].flat(Infinity) // [1] |
|
Thanks! This is great! |

!= null is shorter and achieves the same thing.

This PR was manually merged in 0.12.1 release. However, @FredericHeem doesn't show up as the contributor of this repo despite I explicitly listed @FredericHeem as the co-author of the commit. Not sure why. This method worked previously in another commit, though. Nonetheless, I manually added @FredericHeem in the contributor list of the README.md file. |
This PR solves #16, allowing simpler client's code.
