bindAll ( ob , fns , selected )

#### API
- ob - Object to bind methods to.
- fns - is an object whose values get fixed bound to ob

optional

- selected - Array of string providing names of selected functions to bind - in case when binding needs to be done selectively.

#### Install

``
npm install @badhands/bindAll
`


#### Internals

- reassign `.this` to fixed object for selected functions

- mutates fns that holds the functions

- Other implementation ( lodash, underscore ) of bindAll does not provide option to control what fns is bound to.

- 40 lines of code.



#### Examples

. . binding all functions in object

| livescript |
| --- |

`javascript
bindAll = require("@badhands/bindAll")

ob =
{
fuel:"coffee",
fns:
{
foo:function(){
console.log(this)
}
}
}


ob.fns.foo() // { foo: [Function: foo] } // cannot access .fuel :(

bindAll(ob,ob.fns) // will mutate original object

ob.fns.foo() // { fuel: 'coffee', fns: { foo: [Function] } }
// can access .fuel now !
`

. . for applying to a subset number of functions

| livescript |
| --- |

`javascript
ob =
{
fuel:"coffee",
fns:
foo:function()
{
console.log(this)
}
bar:function()
{
console.log(this)
}
}

bindAll(ob , ob.fns , ["bar"])

ob.fns.bar()
// { fuel: 'coffee', fns: { log: [Function] , bar: [Function] } }

ob.fns.foo()
// { fns: { log: [Function] , bar: [Function] } }
