A object compare module

Installation

Usage

    var compare = require('object-compare-function');
    var result = compare({name: 'object1'}, {name: 'object2'});

    console.log(result);

Test

    var assert = require('assert');
    var compare = require('./index.js');

    var result = compare({l: 1}, {l: 1});
    assert(true === result, 'expected true');

    result = compare({l: 1}, {l: 2});
    assert(false === result, 'expected false');

    result = compare({l: 1, key: {}}, {l: 1, key: {}});
    assert(true === result, 'expected true');

    result = compare({l: 1, key: {}}, {l: 1, key: null});
    assert(false === result, 'expected false');

    result = compare({l: 1, key: null}, {l: 1, key: null});
    assert(true === result, 'expected true');

    result = compare({l: 1, key: null}, {l: 1, key: undefined});
    assert(false === result, 'expected false');

    result = compare({
        level: 1,
            one: {
            level: '2',
            two: {
                level: 3,
                three: [{
                    'four-1': [1, '2', {five: 'deep'}],
                    'four-2': [1, 2, 3, ['a', 'b', 'c']]
                }]
            }
          },
          name: 'object'
    }, {
        level: 1,
        one: {
            level: '2',
            two: {
                level: 3,
                three: [{
                    'four-1': [1, '2', {five: 'deep'}],
                    'four-2': [1, 2, 3, ['a', 'b', 'c']]
                }]
            }
        },
        name: 'object'
    });
    assert(true === result, 'expected true');

    result = compare({
        level: 1,
        one: {
            level: '2',
            two: {
                level: 3,
                three: [{
                    'four-1': [1, '2', {five: 'deep???'}],
                    'four-2': [1, 2, 3, ['a', 'b', 'c']]
                }]
            }
        },
        name: 'object'
    }, {
        level: 1,
        one: {
            level: '2',
            two: {
                level: 3,
                three: [{
                    'four-1': [1, '2', {five: 'deep'}],
                    'four-2': [1, 2, 3, ['a', 'b', 'c']]
                }]
            }
        },
        name: 'object'
    });
    assert(false === result, 'expected false');

    result = compare([{}, [{key: null}]], [{}, [{key: null}]]);
    assert(true === result, 'expected true');

    result = compare([{}, [{key: null}]], [{}, [{key: undefined}]]);
    assert(false === result, 'expected false');

Note

This module use === operator instead of == operator, so you will get false when {key: false} {key: null} {key: undefined} {key: 0} {key: NaN} {key: ''} is compared each other.
