Source

deep-freeze-strict

recursively Object.freeze() objects.

this fork works in strict mode, so when freezing a function you don't get the error:

> (function(){ "use strict"; deepFreeze(function(){}); })();

TypeError: 'caller', 'callee', and 'arguments' properties may not be accessed on strict mode functions or the arguments objects for calls to them

example

var deepFreeze = require('deep-freeze-strict');

deepFreeze(Buffer);
Buffer.x = 5;
console.log(Buffer.x === undefined);

Buffer.prototype.z = 3;
console.log(Buffer.prototype.z === undefined);

$ node example/deep.js
true
true

methods

var deepFreeze = require('deep-freeze-strict')

deepFreeze(obj)

Call Object.freeze(obj) recursively on all unfrozen properties of obj that are functions or objects.
