# Fable.Extras [![Nuget](https://img.shields.io/nuget/v/Fable.Extras.svg?maxAge=0&colorB=brightgreen&label=Fable.Extras)](https://www.nuget.org/packages/Fable.Extras)

A more functional construct on-top of Fable.Core.

Near-zero bundle size, as almost the entire library is erased at compile time.

Documentation can be found [here](https://shmew.github.io/Fable.Extras/).

### A quick look:

#### JS Maps

```fsharp

open Fable.Extras

JSe.Map.empty

|> JSe.Map.set 1 1

|> JSe.Map.set 2 4

|> JSe.Map.values

|> List.sum // 5

```

#### JS Regular Expressions and String extensions

```fsharp

open Fable.Extras

let pattern = JSe.RegExp("^[0-9]")

"20 foxes jumped over the bridge".Replace(pattern, "numbers") 

// "numbers foxes jumped over the bridge"

```

#### Or assignment chaining

```fsharp

open Fable.Extras

open Fable.Extras.Operators

let maybeInt = None ?| Some 1 ?| None ?| Some 2 // Some 1

```

#### Web Assembly

```fsharp

open Fable.Extras

open Fable.Extras.WebAssembly

// Wasm binding

type WasmFableExports =

    abstract add: int * int -> int

async {

    let! wasmBinary = ... // HttpResponse

    return! WA.compileStreaming(wasmBinary)

}

...

wasmInstance.add(1,2) // 3

```
