# defaults
> A simple one level options merge utility
## Install
```sh
npm install defaults
```
## Usage
```js
const defaults = require('defaults');
const handle = (options, fn) => {
options = defaults(options, {
timeout: 100
});
setTimeout(() => {
fn(options);
}, options.timeout);
}
handle({timeout: 1000}, () => {
// We're here 1000 ms later
});
handle({timeout: 10000}, () => {
// 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.
