Benchmark: jQuery old vs Vanilla JS GetID Speed Test

jQuery old vs Vanilla JS GetID Speed Test (version: 0)

Comparing speed of getting element by id with jQuery vs Vanilla JS

Comparing performance of: getElementById() vs getElementsByClassName() vs getElementsByTagName() vs querySelector(#id) vs querySelector(.id) vs querySelectorAll(#id) vs querySelectorAll(.id) vs jQuery(#id) vs jQuery(.id) vs jQuery(tag#id) vs jQuery(tag.id) vs jQuery + getElementById vs jQuery + getElementsByClassName vs jQuery + querySelectorAll

Autogenerated LLM Summary (model llama3.2:3b, generated 6 months ago):

It seems like you're providing a JSON-like string representing some kind of data. I'll help you parse it and extract insights.

The provided data appears to be a list of test results, each with the following properties:

RawUAString: A raw User Agent (UA) string from various browsers.
Browser: The browser name extracted from the RawUAString.
DevicePlatform: The device platform (Desktop in this case).
OperatingSystem: The operating system (Windows).
ExecutionsPerSecond: The number of executions per second for a specific test.
TestName: The name of the test.

There are 8 test results, each representing a different query or scenario:

querySelector(#id)
jQuery + getElementById
querySelectorAll(.id)
jQuery(#id)
querySelectorAll(#id)
jQuery(.id)
jQuery(tag.id)
jQuery(tag#id)

If you'd like, I can help you with:

Identifying the most common browsers and their executions per second
Finding the slowest test results
Extracting insights from the data

Please let me know how I can assist you further!
