Semalt bietet einen Vergleich von Javascript mit anderen Sprachen für Web Scraping

JavaScript (abgekürzt als JS) ist ein dynamisches Multi-Paradigma und High-Level Programmiersprache. Genau wie Python, HTML, CSS und Ruby wird JavaScript verwendet, um Websites interaktiv zu machen und Daten aus dem Netz zu scrappen. Fast alle Websites und Blogs verwenden JavaScript, und die modernen Webbrowser unterstützen es aufgrund seiner eingebauten Engines.

Rolle von JavaScript im Web-Scraping:

Als Multi-Paradigma-Sprache unterstützt JavaScript verschiedene Web-Scraping- und Datenextraktionsprojekte. Es verwendet eine API zum Scrappen von Text und Bildern und zum Arbeiten mit regulären Ausdrücken. Die JavaScript-Engines sind in verschiedene Arten von Scraping-Software eingebettet und helfen Ihnen, sofort lesbare und skalierbare Daten auf Ihre Festplatte herunterzuladen.

Java und JavaScript - Die beste Sprache für Web-Scraping:

Es gibt verschiedene Ähnlichkeiten zwischen Java und JavaScript, einschließlich Sprachnamen, Standardbibliotheken und Syntax. Dennoch ist JavaScript viel besser als Java und wird häufig verwendet, um Web Scraping- und Screen Scraping-Software zu erstellen. Manchmal sind die Daten, die wir abkratzen wollen, nicht in der organisierten Form vorhanden. Es kann dynamisch generiert werden (mit AJAX, Cookies und Redirects). Es ist möglich, unorganisierte und rohe Daten in die strukturierte und organisierte Form mit spezifischen JavaScript-Codes umzuwandeln. Im Vergleich dazu bietet Java eine begrenzte Anzahl von Funktionen und Optionen und macht es uns schwer, Daten richtig zu organisieren.

JavaScript und Python:

Leider ist JavaScript nicht so effektiv wie Python. Die Python-Bibliotheken spielen eine bedeutende Rolle beim Web-Scraping. BeautifulSoup und Scrapy werden beispielsweise häufig verwendet, um Daten aus dynamischen Websites, HTML und XML zu extrahieren Dateien, PDF-Dokumente und private Blogs. Außerdem arbeitet Python mit Ihrem bevorzugten Parser und bietet idiomatische Möglichkeiten zum Navigieren, Suchen und Ändern eines Parse-Baums. Es spart Ihnen Zeit und Energie und stellt die Bereitstellung von gut gecrappten Daten sicher. Python hilft bei der Durchführung komplexer Datenschaber-Projekte, und wir können mehrere Aufgaben gleichzeitig erledigen.

Vergleich von JS und Ruby:

Ruby ist gut in Produktionsbereitstellungen und Stringmanipulationen in Ruby weit besser als JavaScript Auch hilft Ruby bei der Analyse der Webseiten und macht es uns leicht, Inhalte zu scrappen. Es kann mit zerbrochenen HTML-Dateien umgehen und kann sofort Daten von ihnen abkratzen. Leider ist JavaScript nicht in der Lage von Scrapi ng Daten aus defekten XML- und HTML-Dateien. Ruby hat auch verschiedene Erweiterungen, wie Luffa und Sanitize, die helfen, die gebrochenen HTML-Codes aufzuräumen. Der einzige Nachteil von Ruby ist, dass es kein maschinelles Lernen und keine NLP-Toolkits gibt.

Fazit:

Wenn Sie regelmäßig Daten von dynamischen oder komplexen Websites scrappen möchten, ist JavaScript nicht die richtige Sprache für Sie. Sie können jedoch JavaScript-basierte Traffic-Tracking-Tools (wie Google Analytics) verwenden, um andere Aufgaben auszuführen. In dieser datengesteuerten Welt müssen Sie ständig wachsam sein, da sich die Informationen ständig ändern. Mit JavaScript ist es nicht möglich, lesbare und skalierbare Daten effizient zu erhalten. Es bedeutet, dass sowohl Ruby als auch Python weit besser sind als JavaScript und Hilfe  Informationen  von mehreren Webseiten abkratzen. JS eignet sich nur zum Erstellen von einfachen Web-Crawlern und Daten-Scrapern. Es ist einfach zu programmieren und ermöglicht es uns, unsere Webseiten zu indizieren, ohne irgendeinen Teil unseres Codes zu blockieren.
