hnt is useful but sometimes you want to do things other than just access a value.

For example you may want to get a value and if that value is a certain number to greater than a certain number you may want to do something. In other words you might want to use hnt for equality checks:

import { eql } from "hnt";

// first two params are the same as hnt, last param is what value should be checked
// if deepArray[0][0][0] === 0 then eql will return true, 
// otherwise (if it is undefined or equals something else) it will return false
eql(deepArray, "[0][0][0]", 0);

Consider this:

import hnt from 'hnt'

function getResult(): any[] | null {
  ...
}

const result = getResult()
console.log(htn(result, 'data[0]', {})

With the signature as it stands, the console would fail. Rather than having to explicitly check if array's null before passing it on to htn, it would be desirable to do so implicitly:

export function hnt(array: any[] | null, path: string, fallback: any) {
  if (array === null) return fallback
  ...

Right now way of writing the access path is a little weird (you need to write it 'relative' to the array you pass in). Maybe it would be easier you could pass in the full access path.

i.e.
now assuming you have this array:

let array = [{ name: "divy" }]

you have to do this:

let accessPath = "[0].name"

but it might be better to allow both that and this:

let accessPath = "array[0].name"
