    As a multi-paradigm language, JS (JavaScript) supports functions, event-driven and imperative (such as prototype-based and object-oriented) programming styles. It is best known for its interactive API and helps download a webpage comfortably. Plus, JavaScript is used to work with arrays, text, regular expressions, dates and the primary manipulation of DOM.

    With JavaScript, the downloading webpage is very easy, but you would have to learn some codes and understand the programming syntax. Here we have discussed the best and most potent JavaScript plugins and frameworks to download webpage comfortably.

    1. iCheck:

    It is a jQuery plugin that enhances the look of a webpage. You can use iCheck to download webpage and store it on your hard drive for offline uses. To get benefited from iCheck, you would have to include the CSS and JS files on your site and convert the raw data to readable and scalable information with just a few lines of jQuery.

    2. Shave:

    It is a zero dependency JavaScript plugin that is used to transform unorganized data into an organized and structured form. Shave is the prior choice of web developers and programmers and helps them download webpage without any need for sophisticated codes. You can also use Shave to truncate the multi-line text to fit within an HTML element. Shave requires a Max height and a Selector to perform its task and allows you to download simple and dynamic web pages in a few minutes.

    3. Jschema.js:

    Jschema.js is one of the best and most famous JavaScript frameworks. It is primarily used for modeling data in both Node and JavaScript. You can easily download webpage or images of a site with this framework. Jschema.js uses fundamental data modeling principles similar to what you would see in a traditional SQL-based database. 

    Plus, its API makes it easy for you to aggregate the datasets and manage your web scraping tasks. By encapsulating all information into a single object, jschema.js can retain the metadata about the tables and provides a simple interface for manipulating, accessing, slicing and updating it. Plus, it allows us to work with tabular data, and we can also filter the data based on its quality and target keywords.

    4. D3.js:

    Just like Jschema.js, D3.js is a famous JavaScript library to download webpage. It is primarily used for manipulating the web documents and allows you to bring life to your web pages using CSS, SVG, and HTML. This JavaScript framework gives you full control over your web browser, and you can combine different web documents to boost your own business. 

    It either works individually or is combined with other JavaScript frameworks and libraries to download webpage easily. You can also apply the data-driven transformation to your web documents and can use D3.js to generate HTML tables and charts. With minimal overhead, D3.js is a powerful library that allows you to build basic web scrapers and data extractors.

    Because JavaScript is the only language that the most popular web browsers support, it has become the best language for building data scrapers and downloading web pages in multiple languages.
