Package Exports

deep-unfreeze

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (deep-unfreeze) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

deep-unfreeze

Unfreeze a JavaScript object/array/function that has previously been frozen (and deeply frozen) with Object.freeze, by doing a copy.

Usage

import deepUnfreeze from 'deep-unfreeze';

let subject,
    result;

subject = {};

Object.freeze(subject);

// Doesn't add the property.
// subject.lorem = 'LOREM';

result = deepUnfreeze(subject);

result.lorem = 'LOREM';

import deepUnfreeze from 'deep-unfreeze';

let subject,
    result;

subject = [];

Object.freeze(subject);

// Throws an error.
// subject.push('LOREM');

result = deepUnfreeze(subject);

result.push('LOREM');

import deepUnfreeze from 'deep-unfreeze';

let subject,
    result;

subject = function() {
};

Object.freeze(subject);
Object.freeze(subject.prototype);

// This won't work.
// subject.prototype.sayLorem = function() { console.log('LOREM'); };
// new subject().sayLorem() // TypeError: (intermediate value).sayIpsum is not a function

result = deepUnfreeze(subject);

result.prototype.sayIpsum = function() { console.log('IPSUM'); };
// new result().sayIpsum() // "IPSUM"
