`zames` converts callback-based functions to Promises and apply currying to arguments.
`zames` = [currify][currify] + [promisify][promisify].
## Install
`npm i zames --save`
## API
### zames(fn [,ctx])
- `fn` - function
- `ctx` - context
`zames` can take just a `function`:
```js
const zames = require('zames');
const promise = zames((a, b, fn) => {
fn(null, a + b);
});
const add = promise('hello ');
add('world').then((a) => {
console.log(a);
// output
'hello world';
});
```
Or can be used with `ctx` as well:
```js
const ctx = {
error: 'hello',
log: function(a, b, fn) {
fn(this.error);
}
}
const withContext = zames(ctx.log, ctx);
withContext(1, 2)
.catch((e) => {
console.error(e.message);
// output
'hello';
});
```
