Benchmark Overview

The provided benchmark measures the performance of two approaches for concatenating HTML strings and appending them to an HTML element: using a template node or using string concatenation.

Template Node Approach

This approach uses the cloneNode method to create multiple instances of an HTML template, which is stored in the #product-card-template element. The cloned templates are then appended to the #cards section.

// Create a template
var templateCards = document.querySelector('#product-card-template');

String Concatenation Approach

This approach uses string concatenation to build an HTML string and then appends it to the #cards section.

// Define an HTML string
var cardInnerHTML = `<div class="product-card">
        <img class="product-card__photo" src="#" alt="" />
        <div class="product-card__text-container">
            <h3 class="product-card__title"></h3>
            <p class="product-card__cost"></p>
        </div>
        <div class="product-card__button-container">
            <button class="product-card__order-button" type="button">Заказать</button>
            <button class="product-card__basket-button" type="button">В корзину</button>
        </div>
    </div>`;

// Append the HTML string to the section
var sectionCards = document.querySelector('.cards');
sectionCards.innerHTML += cardInnerHTML;

Options Compared

The two approaches are compared in terms of their execution speed. The benchmark aims to measure which approach is faster for large datasets.

Pros and Cons of Each Approach

Template Node Approach:

Pros:

• More efficient use of DOM elements, as the cloned templates are re-used
• Can reduce the number of DOM mutations

Cons:

• Requires creating a template element upfront
• Cloning can be slower than concatenation

String Concatenation Approach:

Pros:

• Simpler to implement and maintain
• Does not require creating a template element upfront

Cons:

• Creates multiple DOM elements, which can lead to performance issues
• Can result in more DOM mutations

Library Used

In this benchmark, the cloneNode method is used from the DOM API. This method creates a new copy of an existing node, preserving its attributes and child nodes.

Special JS Feature/Syntax

The benchmark does not use any special JavaScript features or syntax, such as ES6 classes or async/await.

Alternative Approaches

Other approaches that could be considered for this benchmark include:

• Using a library like React or Angular to manage the DOM
• Using a string concatenation library like Underscore.js
• Using a templating engine like Handlebars

However, these alternatives may introduce additional overhead and complexity, making them less suitable for a simple benchmark like this one.
