Ugly but fast read only object

This module actually don't freeze object but convert the object into nested functions. Hence accessing any propery seems ugly.

How to use

Install like any npm package

npm i fast-freeze

then just use it

var fastFreeze = require("fast-freeze");

var testConfig = var C = {
    name: 'John',
    surname: 'Johnson',
    age: 26,
    address: {
        street: '1st Street',
        city: 'Los Angeles',
        country: 'USA'
    vehicles: [

var frozenConfig = fastFreeze(C);

console.log( frozenConfig("vehicles")[1] );
console.log( testConfig["vehicles"][1] );
