# defaults
A simple one level options merge utility
## install
`npm install defaults`
## use
```javascript
var defaults = require('defaults');
var handle = function(options, fn) {
options = defaults(options, {
timeout: 100
});
setTimeout(function() {
fn(options);
}, options.timeout);
}
handle({ timeout: 1000 }, function() {
// we're here 1000 ms later
});
handle({ timeout: 10000 }, function() {
// we're here 10s later
});
```
## summary
this module exports a function that takes 2 arguments: `options` and `defaults`. When called, it overrides all of `undefined` properties in `options` with the clones of properties defined in `defaults`
Sidecases: if called with a falsy `options` value, options will be initialized to a new object before being merged onto.
