Benchmark: indexof vs object lookup vs if OR

Tests:

indexof
var payload = "negativeUnsure"; var body = document.getElementsByTagName("BODY")[0]; var mArr = ["positiveFeedback", "negativeFeedback", "positiveAnotherQ", "negativeAnotherQ", "positiveAssistant", "negativeAssistant", "Visor", "Assistant", "clickWhileOnPhase", "afterCancelConversation", "positiveUnsure", "negativeUnsure", "Link to FAQ"] if(mArr.indexOf(payload) !== -1) body.innerHTML += "<div></div>";
object lookup
var payload = "negativeUnsure"; var body = document.getElementsByTagName("BODY")[0]; var mObj = { positiveFeedback: true, negativeFeedback: true, positiveAnotherQ: true, negativeAnotherQ: true, positiveAssistant: true, negativeAssistant: true, Visor: true, Assistant: true, clickWhileOnPhase: true, afterCancelConversation: true, positiveUnsure: true, negativeUnsure: true, "Link to FAQ": true } if(mObj[payload]) body.innerHTML += "<div></div>";
If OR
var payload = "negativeUnsure"; var body = document.getElementsByTagName("BODY")[0]; if(payload === "positiveFeedback" || payload === "negativeFeedback" || payload === "positiveAnotherQ" || payload === "negativeAnotherQ" || payload === "positiveAssistant" || payload === "negativeAssistant" || payload === "Visor" || payload === "Assistant" || payload === "clickWhileOnPhase" || payload === "afterCancelConversation" || payload === "positiveUnsure" || payload === "negativeUnsure" || payload === "Link to FAQ"){ body.innerHTML += "<div></div>" }

Let's dive into the benchmark.

The test cases on MeasureThat.net compare three different approaches to check if a specific value exists in an array or object:

1. **IndexOf**: This approach uses the `indexOf()` method of the array, which returns the index of the first occurrence of the specified value. If the value is not found, it returns -1.
2. **Object Lookup**: This approach uses the property access syntax (`mObj[payload]`) to check if a specific key exists in the object.
3. **If OR**: This approach uses an `if` statement with multiple conditions, where each condition checks if the value matches one of several possible values.

Now, let's discuss the pros and cons of each approach:

**IndexOf**:

Pros:

* Fast and efficient
* Works well for large arrays

Cons:

* Returns -1 if the value is not found, which can lead to unnecessary comparisons in subsequent code
* May be slower than other approaches if the array is very large

**Object Lookup**:

Pros:

* More readable and expressive than `indexOf()`
* Works well for objects with a small number of properties

Cons:

* May be slower than `indexOf()` due to the overhead of property access
* Requires the object's structure to be known beforehand

**If OR**:

Pros:

* Simple and easy to understand
* Can be useful when working with variable numbers of conditions

Cons:

* Slow and inefficient, especially for large arrays or objects
* May lead to code bloat if multiple conditions are used

The choice of approach depends on the specific use case and requirements. For example, if you need to perform a large number of checks in a short amount of time, `indexOf()` might be the best choice. However, if readability is more important, Object Lookup or If OR might be preferred.

In this benchmark, the results show that **IndexOf** performs the fastest, followed by **If OR**, and then **Object Lookup**. This suggests that the array size and object structure used in these tests favor the `indexOf()` approach.
