A brand new proposal to TC39 for an Object.fromEntries, that produces the inverse effect of Object.entries. With Object.entries, you get an iterator of [key, value] pairs in an object. With Object.fromEntries, you can cast [key, value] pairs into objects. Simple, nice, and it would offer a solution for one of those rare operations that even lodash doesn’t get quite right (even using the powerful utility library we often need to resort to several function calls in a row). |

“A Collection of Anecdotes from the Evolutionary Computation and Artificial Life Research Communities” “Evolution provides a creative fount of complex and subtle adaptations that often surprise the scientists who discover them. However, the creativity of evolution is not limited to the natural world: artificial organisms evolving in computational environments have also elicited surprise and wonder from the researchers studying them.” An amusing paper indeed! Here is one of the funnier videos. |

Preethi explains: “Knockout text is a technique where words are clipped out of an element and reveal the background. In other words, you only see the background because the letters are knocking out holes. It’s appealing because it opens up typographic styles that we don’t get out of traditional CSS properties, like color.” |
