Understanding the Benchmark
The provided benchmark measures the performance difference between creating new DOM elements using JavaScript's document.createElement()
method versus jQuery's $
function to create HTML elements.
In essence, the benchmark is testing how efficiently each approach can create 100,000 new HTML elements (div) and add them to an array. The test aims to determine which method is faster in creating these elements.
Approaches Compared
There are two main approaches being compared:
document.createElement()
This method uses the native DOM API to create a new element. It's a straightforward approach that involves calling the createElement()
method and passing the desired HTML element as an argument.$
function
The jQuery library provides a shorthand way to create HTML elements using its $
function. This approach wraps the creation of the element in a more concise syntax, making it easier to write code.Pros and Cons

.Pros:
$

Library Used
In this benchmark, jQuery is used as a library to compare with native JavaScript. The jQuery library provides the $
function, which wraps element creation in a more concise syntax.
Special JS Feature/ Syntax
There are no special JavaScript features or syntaxes explicitly mentioned in the provided benchmark definition. However, note that using const x = document.createElement('div');
and x.classList.add('tabs');
is an example of using modern JavaScript features (ES6+), such as constant declarations (const
) and template literals (\t
).
Other Alternatives
If you're looking for alternative approaches or libraries to create DOM elements, consider the following:
Keep in mind that each approach has its strengths and weaknesses, and choosing the right one depends on your project's specific requirements and performance needs.
