Benchmark: Which operator (== vs >) is faster?

Tests:

test equality
var n = 0; while(true) { n++; if(n==100000) break; }
test greater than
var n = 0; while(true) { n++; if(n<99999) break; }

I'd be happy to explain the benchmark and its results.

**Benchmark Definition**

The benchmark, as defined in the JSON file, is designed to compare the performance of two operators: `==` (equality) and `>` (greater than). The idea behind this comparison is to determine if there's a significant performance difference between using equality checks versus simple value comparisons.

**Options Compared**

In this benchmark, two options are being compared:

1. **Equality Check (`==`)**: This option involves using the `==` operator to compare values.
2. **Simple Value Comparison (>)**: This option involves using the `>` operator for simple value comparisons without equality checks.

**Pros and Cons of Each Approach**

*   **Equality Check (`==`)**
    *   Pros:
        *   Readability: Equality checks can make code more readable, especially in cases where the comparison is conditional.
        *   Maintainability: Using equality checks ensures that if one part of the condition changes, the entire expression doesn't have to be changed.
    *   Cons:
        *   Performance Overhead: Equality checks are generally slower than simple value comparisons due to the additional step required for the `===` operation (which also performs type checking).
*   **Simple Value Comparison (`>`)**
    *   Pros:
        *   Speed: Simple value comparisons are faster than equality checks, which is beneficial in performance-critical code paths.
    *   Cons:
        *   Lack of Readability: Using simple value comparisons without explicit checks can make code harder to understand and maintain.

**Library Usage**

In the provided test cases, there doesn't appear to be any specific JavaScript library being used for benchmarking. However, libraries like Benchmark.js or JSPerf might be used to run these tests on different browsers or environments if needed.

**Special JS Features/Syntax**

The test case uses a `while` loop and some basic arithmetic operations (`++`, `<`). There's no special JavaScript feature or syntax being utilized in this benchmark. The focus is solely on comparing the performance of equality checks versus simple value comparisons.

**Other Alternatives**

For those interested in running similar benchmarks, there are other alternatives like:

*   **Benchmark.js**: A popular library for writing fast and accurate microbenchmarks.
*   **JSPerf**: A JavaScript testing framework that allows you to run benchmarks on different browsers and environments.
