Benchmark: Conditionals (if-else, ternary, switch, object-function, object-plain) with last evaluation v3 (with obj-get!)

Tests:

Object-Function
(({ 'object'(){return 'object'}, 'boolean'(){return 'boolean'}, 'function'(){return 'function'}, 'string'(){return 'string'} //the condition used to filter an object above })[typeof 'string']||(()=>'undefined'))()
Object-plain
({ 'object':'object', 'boolean':'boolean', 'function':'function', 'string':'string' //the condition used to filter an object above })[typeof 'string']||'undefined'
If-Else
if(typeof 'string'==='object'){return 'object'} else if(typeof 'string'==='boolean'){return 'boolean'} else if(typeof 'string'==='function'){return 'function'} else if(typeof 'string'==='string'){return 'string'} else { return 'undefined' }
Ternary
typeof 'string'==='object'?'object': typeof 'string'==='boolean'?'boolean': typeof 'string'==='function'?'function': typeof 'string'==='string'?'string': 'undefined';
Switch
switch (typeof 'string') { case 'object': return 'object'; break; case 'boolean': return 'boolean' break; case 'function': return 'function'; break; case 'string': return 'string'; break; default: 'undefined'; }
Object-Get
({ get 'object'(){return 'object'}, get 'boolean'(){return 'boolean'}, get 'function'(){return 'function'}, get 'string'(){return 'string'} //the condition used to filter an object above })[typeof 'string']||'undefined'

Let's break down the provided benchmark definition and test cases to understand what's being tested.

**Overview**

The benchmark is designed to stress-test different approaches for condition searching in JavaScript, including various data types (object, boolean, function, string). The goal is to identify the fastest approach.

**Options Compared**

Four options are compared:

1. **Object-Function**: Uses an object with methods that return a specific value based on the type of the input string.
2. **Object-Plain**: Uses an object with properties that return a specific value based on the type of the input string.
3. **If-Else**: Uses traditional if-else statements to check the type of the input string.
4. **Ternary**: Uses ternary operators to concisely express the same logic as If-Else.
5. **Switch**: Uses switch statements to check the type of the input string.
6. **Object-Get**: Uses an object with getter methods that return a specific value based on the type of the input string.

**Pros and Cons**

Here's a brief summary of each approach:

1. **Object-Function**: Pros: concise, readable; Cons: might be slower due to method calls.
2. **Object-Plain**: Pros: similar performance to Object-Function; Cons: less readable.
3. **If-Else**: Pros: widely supported, easy to understand; Cons: can be slower and more verbose.
4. **Ternary**: Pros: concise, fast; Cons: limited readability.
5. **Switch**: Pros: fast, readable; Cons: requires exact type names.
6. **Object-Get**: Pros: similar performance to Object-Function; Cons: less readable.

**Library**

None of the test cases use external libraries.

**Special JS Features/Syntax**

No special JavaScript features or syntax are used in these test cases.

**Other Considerations**

When choosing a condition searching approach, consider factors such as:

* Readability: How easy is the code to understand and maintain?
* Performance: What's the execution time for each approach?
* Browser support: Are all browsers supported equally?

**Alternatives**

If you need more flexibility or customization options, consider using:

1. **Template literals**: Can be used with Switch statements for more readable type checks.
2. **Type guards**: Can be used with If-Else statements for more robust type checking.
3. **Object destructuring**: Can be used to simplify Object-Plain and Object-Get approaches.

Keep in mind that each approach has its strengths and weaknesses, and the best choice depends on your specific use case and performance requirements.
