Benchmark: Lodash.get with an instance default and validation of result

HTML Preparation code:


<script src='https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.5/lodash.min.js'></script>

Script Preparation code:

var obj = {
   test: new Set([1])
}

Tests:

With new instance in get default
var t1 = _.get(obj, 'test', new Set()); var t2 = _.get(obj, 'missing', new Set()); t1.has(1); t2.add(2);
Boolean logic with lodash
var t1 = _.get(obj, 'test', false) ? _.get(obj, 'test') : new Set(); var t2 = _.get(obj, 'missing', false) ? _.get(obj, 'missing') : new Set(); t1.has(1); t2.add(2);
Boolean logic only
var t1 = !!obj.test ? obj.test : new Set(); var t2 = !!obj.missing ? obj.missing : new Set(); t1.has(1); t2.add(2);

Let's dive into the world of JavaScript microbenchmarks and analyze what's being tested on MeasureThat.net.

**Benchmark Definition**

The benchmark is created using JSON, which defines two test cases:

1. **Lodash.get with an instance default and validation of result**: This test case measures the performance of Lodash's `get` function when used with an instance default value and validation of the result.
2. The second test case is a variant of the first one, but uses Boolean logic to determine whether to create a new instance or return the existing value.

**Script Preparation Code**

The script preparation code defines a JavaScript object `obj` with a property `test`, which is initialized as a new Set containing only the number 1.

```javascript
var obj = {
   test: new Set([1])
};
```

This object will be used in the benchmark tests.

**Html Preparation Code**

The HTML preparation code includes a script tag that loads the Lodash library, version 4.17.5.

```html
<script src='https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.5/lodash.min.js'></script>
```

This library provides various utility functions, including `get`, which is used in the benchmark tests.

**Individual Test Cases**

There are three test cases:

1. **With new instance in get default**: This test case uses Lodash's `get` function with an instance default value and validation of the result.
```javascript
var t1 = _.get(obj, 'test', new Set());
var t2 = _.get(obj, 'missing', new Set());
```

**Pros and Cons:**

* **Using an instance default value**: This approach can be beneficial when you want to ensure that a specific property is always created if it doesn't exist. However, it may incur additional overhead due to the creation of a new instance.
* **Validation of result**: Adding validation to the `get` function can make it more robust but also increases the complexity and potentially the execution time.

**Boolean Logic with Lodash**

The second test case uses Boolean logic to determine whether to create a new instance or return the existing value.

```javascript
var t1 = _.get(obj, 'test', false) ? obj.test : new Set();
var t2 = _.get(obj, 'missing', false) ? obj.missing : new Set();
```

**Pros and Cons:**

* **Using Boolean logic**: This approach can be more efficient than creating a new instance for all cases. However, it may require additional logic to handle the `false` value.

**Boolean Logic Only**

The third test case uses only Boolean logic without Lodash's `get` function.

```javascript
var t1 = !!obj.test ? obj.test : new Set();
var t2 = !!obj.missing ? obj.missing : new Set();
```

**Pros and Cons:**

* **Simpler approach**: This method is straightforward but may not be as efficient or flexible as the other approaches.

**Library: Lodash**

Lodash is a utility library that provides various functions for tasks such as string manipulation, array manipulation, and more. The `get` function is used in this benchmark to access nested properties of an object.

**Special JS Feature/Syntax: None**

There are no special JavaScript features or syntaxes mentioned in the provided code.

**Other Alternatives**

If you need to optimize your code for performance or use different approaches, consider the following alternatives:

* Use a different library, such as Underscore.js or Ramda.
* Implement custom logic to access nested properties.
* Use a different data structure, such as an object with default values.

Keep in mind that these alternatives may require additional overhead and complexity.
