Let's dive into the world of MeasureThat.net, where JavaScript microbenchmarks come to life!
Benchmark Overview
The provided JSON represents a benchmark test case that compares the performance of two approaches: using a numeric value (3
) and a string representation of the same value ('3'
) in the hasOwnProperty
method.
Options Being Compared
Two options are being compared:
3
as the key in the object.'3'
as the key in the object.Pros and Cons of Each Approach
Library Used
None, as this benchmark is a basic JavaScript test case without any external libraries or dependencies.
Special JS Feature/Syntax
The hasOwnProperty
method is a built-in JavaScript method that checks if an object has the specified property as its own property (i.e., not inherited from its prototype chain). It's a common and useful method in many JavaScript scenarios.
Benchmark Preparation Code Explanation
The script preparation code defines an object obj
with several properties, including one with a numeric key (3
) and another with a string representation of the same value ('3'
). This object is used as the test subject for the benchmark.
Individual Test Cases
Each individual test case consists of two parts:
hasOwnProperty
method.Latest Benchmark Result
The provided JSON result shows the benchmark execution data for two test cases:
These results suggest that using numeric values is faster than using string representations in the hasOwnProperty
method.
Other Alternatives
If you're interested in exploring other benchmarking platforms or approaches, some alternatives include:
