Examples

. . binding all functions in object

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

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] } }
