flatMap in Scala are used to generate a separate set of sequence it is used with collection data structures and we can also use them with mutable and immutable collection objects. It also helps in faster processing of collection elements by making them parallel.

The flat() and flatMap() functions are available in Chrome 69 / V8 6.9, so you need Node.js 11. Array#flat() is analogous to Lodash's _.flattenDepth() function. The flat() function takes an array of arrays and "flattens" the nested arrays into the top-level array.

To avoid malicious use, npm is hanging on to the package name, but loosely, and we'll probably give it to you if you want it. Given is the following js command: [].flat; Executing it in a browser (chrome/firefox): returns function. Executing it with nodejs v10.13.0: returns undefined. Now I am wondering what other methods are not in the node RTE and where the documentation of global Objects like Array is. Seems to be the same with Array.prototype.flatMap. A widely used npm package, event-stream, has been found to contain a malicious package named flatmap-stream.

This lesson is a quick look at map and flatMap and how they relate. flatMap in Scala are used to generate a separate set of sequence it is used with collection data structures and we can also use them with mutable and immutable collection objects. It also helps in faster processing of collection elements by making them parallel. chain is also known as flatMap in some libraries. Dispatches to the chain method of the second argument, if present, according to the FantasyLand Chain spec. If second argument is a function, chain(f, g)(x) is equivalent to f(g(x), x).
