#### Defaults
`fast-json-stringify` supports `default` jsonschema key in order to serialize a value
if it is `undefined` or not present.

Example:
```javascript
const stringify = fastJson({
title: 'Example Schema',
type: 'object',
properties: {
nickname: {
type: 'string',
default: 'the default string'
}
}
})

console.log(stringify({})) // '{"nickname":"the default string"}'
console.log(stringify({nickname: 'my-nickname'})) // '{"nickname":"my-nickname"}'
```
