# jsoff

Count which JSON fields you've accessed and remove the rest.

```js

const { jsOff, countSymbol } = require('@reconbot/jsoff')

const input = {

  foo: {

    bar: 4,

    baz: null

  },

  arr: [{ name: 'spock', age: 64 }, { name: undefined }]

}

const data = jsOff(input)

console.log(data.foo.bar)

console.log(data.arr.map(i => i.name ))

console.log(data[countSymbol])

// { foo: 1, arr: 1 })

console.log(data.arr[0][countSymbol])

// { name: 1, age: 0 }

console.log(JSON.stringify(data))

// {"foo":{"bar":4},"arr":[{"name":"spock"},{}]}

```
