// { a:1, b: null, c:3 }
```

## Overview

expect(
    extend(
        {
            a: 1,
            b: 2,
            d: {
                a: 1,
                b: [],
                c: { test1: 123, test2: 321 }
            },
            f: 5,
            g: 123,
            i: 321,
            j: [1, 2]
        },
        {
            b: 3,
            c: 5,
            d: {
                b: { first: 'one', second: 'two' },
                c: { test2: 222 }
            },
            e: { one: 1, two: 2 },
            f: [],
            g: (void 0),
            h: /abc/g,
            i: null,
            j: [3, 4]
        }
    )
)
    .toEqual({
        a: 1,
        b: 3,
        d:
        {
            a: 1,
            b: { first: 'one', second: 'two' },
            c: { test1: 123, test2: 222 }
        },
        f: [],
        g: undefined,
        c: 5,
        e: { one: 1, two: 2 },
        h: /abc/g,
