Array.flatMap and Object.fromEntries | JavaScript New Features | Learn JavaScript
#es6 #recentlyuploaded #javascript
Hello All,
In this video, I talk about 2 new features added in JavaScript:
Array.flatMap()
Object.fromEntries()
We all know about Array.flat() and Array.map().
Array.flat() - https://developer.mozilla.org/en-US/d...
Array.map() - https://developer.mozilla.org/en-US/d...
Array.flatMap() is a combination of flat() and map() but a bit faster.
