# function-logger

Awesome tool for [FP JS](https://github.com/stoeffel/awesome-fp-js). Logging of the input and output arguments of the function on each call.

[JSBin demo](https://jsbin.com/sayujal/1/edit?js)

## Motivation

for example, debugging sort products code:

```javascript

const byPrice = order => (a, b) => order(a.price, b.price);

const asc = (a, b) => a - b;

const desc = (a, b) => b - a;

const products = [{price: 100}, {price: 50}, {price: 300}];

// products.sort(byPrice(desc));

// use functionLogger for fast logging

products.sort(functionLogger(byPrice(desc)));

```

browser console output 



### Installation

```

npm install function-logger --save-dev

```

You can set globally, to be used in all their projects without having to install each.

  

## Usage 

Wrap the function for which you want to watch. And yet! :checkered_flag:

```javascript

import functionLogger from 'function-logger';

// foo('bar')

functionLogger(foo)('bar')

```

## Usage for CodePen and JSBin as UMD module

in html area

```javascript

```

in js area use ```functionLogger``` from global scope
