The function will return array of index of first n objects in array which satisfy the query passed.

If the number of objects in array satisfying the query is p which is less than n, then it will return array of index of first p objects in array that satisfy the query

If no object satisfy the condition, null will be returned.

var daex = require('json-daex')
var obj = [
  {
    name: 'abc',
    type: 'array',
    age: 20
  },
  {
    name: 'pqr',
    type: 'string',
    age: 20
  },
  {
    name: 'xyz',
    type: 'array',
    age: 22
  },
  {
    name: 'ghi',
    type: 'array',
    age: 20
  },
  {
    name: 'mno',
    type: 'number',
    age: 20
  }
]

console.log(daex.indexFirstN(obj,{'type':'array'},2))
//get index of first 2 objects with type: array
// Output: [ 0, 2 ]
