Benchmark: Course Completion Benchmark Name

Script Preparation code:

const LMS_COURSE_STATUS_KEY_PARTIAL = {
  COMPLETED: "course_completed",
  STARTED: "access_from"
};

function typedIsCompletedCourse(key) {
  return key.includes(LMS_COURSE_STATUS_KEY_PARTIAL.COMPLETED);
}

function mmmIsCompletedCourse(key) {
  return key[key.length - 1] !== "m";
}

Tests:

Course Completed for typed
for (let i = 0; i < 10000; i++) { typedIsCompletedCourse(`${i}_course_completed`); typedIsCompletedCourse(`course_${i}_access_from`); }
Course Completed for mmmm
for (let i = 0; i < 10000; i++) { mmmIsCompletedCourse(`${i}_course_completed`); mmmIsCompletedCourse(`course_${i}_access_from`); }

Let's break down the benchmark and explain what's being tested.

**Benchmark Overview**

The benchmark is designed to measure the performance of two different approaches to check if a course is completed: `typedIsCompletedCourse` and `mmmIsCompletedCourse`. The test cases involve iterating over 10,000 iterations, calling each function with specific input strings, and measuring the execution time per second.

**Approaches Compared**

The two approaches being compared are:

1. `typedIsCompletedCourse`: This function uses a simple string matching approach to check if a key includes a specific substring (`COMPLETED`).
2. `mmmIsCompletedCourse`: This function also checks if a key includes a specific substring, but it only checks the last character of the string.

**Pros and Cons**

**Typed Is Completed Course**

Pros:

* Simple implementation
* Easy to understand

Cons:

* May be slower due to string matching
* May be vulnerable to optimizations that improve performance at the expense of readability

**Mmm Is Completed Course**

Pros:

* May be faster due to last-character checking
* Less prone to optimizations affecting readability

Cons:

* More complex implementation
* Less intuitive for developers who are not familiar with it

**Other Considerations**

The benchmark does not consider other factors that might affect performance, such as:

* Input data distribution and characteristics
* Browser and device-specific optimizations or limitations
* Code optimization techniques (e.g., caching, memoization)
* Performance-critical functions in the surrounding codebase

**Library Usage**

The `LMS_COURSE_STATUS_KEY_PARTIAL` object is used in both `typedIsCompletedCourse` and `mmmIsCompletedCourse`. This suggests that this object represents a shared constant or configuration value for the benchmark. The purpose of this library is to provide a centralized location for defining course status keys, making it easier to maintain consistency across multiple tests.

**Special JS Feature or Syntax**

There is no explicit mention of any special JavaScript features or syntax being used in the benchmark. However, the use of template literals (`${i}_course_completed`) and function expressions (`function typedIsCompletedCourse(...)` and `function mmmIsCompletedCourse(...)`) are standard JavaScript constructs.

**Alternatives**

If you wanted to create a similar benchmark, you could consider using other approaches to compare performance, such as:

* Using regex patterns instead of simple string matching
* Employing more advanced optimization techniques (e.g., caching, memoization)
* Adding additional test cases with different input characteristics or distributions
* Comparing the performance of different browsers or devices
* Incorporating code optimization techniques into the surrounding codebase

Keep in mind that these alternatives would require significant modifications to the benchmark and its implementation.
