Let's break down the provided benchmarking data and explain what's being tested, compared, and their pros and cons.
Benchmark Overview
MeasureThat.net provides JavaScript microbenchmarks, allowing users to compare different versions of jQuery (a popular JavaScript library for DOM manipulation). The benchmark consists of a script preparation code that creates a simple HTML structure using jQuery and performs some operations on it. The execution time of this script is measured across various browsers and versions.
Test Cases
The benchmark includes four test cases, each testing a specific version of jQuery:
$.noConflict(true)
-wrapped jQuery 1.11.3.$.noConflict(true)
-wrapped jQuery 2.2.4.$.noConflict(true)
-wrapped jQuery 3.3.1.$.noConflict(true)
-wrapped jQuery 3.4.0.Comparison Options
The benchmark compares the execution times of different versions of jQuery, using the same HTML structure and script preparation code. This allows users to compare the performance of each version across various browsers.
Pros and Cons:
Library and Purpose
The $.noConflict(true)
library is used to resolve naming conflicts between jQuery and other libraries. It returns a new object with modified versions of the original jQuery functions, allowing them to coexist without conflicts.
Special JavaScript Features
There are no special JavaScript features mentioned in this benchmarking data.
Other Alternatives
If you're interested in comparing different JavaScript libraries or frameworks for DOM manipulation, consider using alternative benchmarks, such as:
Keep in mind that each alternative has its own strengths and weaknesses, so it's essential to choose the one that best suits your specific needs and requirements.
