# .then log

The js-promise-`.then()`-calls logger for both node.js and browser.

```js

require('thenlog');

Promise.resolve(0)

  .thenlog(v=>v + 1)

  .thenlog(v=>v * 2)

  .thenlog(v=>Math.pow(v, 4))

  .then(v => v)

  .thenlog(v=>v / 0)

  .thenlog(v => {})

  .then(v => 'foobar');

```

## Story en

Promise chains debugging is not too convenient.

You have to replace code shorthands (e.g. `.then(_.union)`) by long statements with a `console.log` instructions.

You have to see many 3th-party call-chains in the browser inspector's debugger in async mode.

And `debugger` injection in node.js for async code debugging using `node debug` is not convenient way again.

## Story ru

Дебажить промисы не очень удобно.

То и дело приходится разорять изящные конструкции вида `.then(_.union)`, внедряя туда `console.log`.

В дебаггере браузера часто приходится смотреть на полотна 3th-party кода.

А в node.js с помощью `node debug` чтобы отлаживать асинхронщину приходится внедрять тут и там `debugger`, что очень неудобно, см. выше.
