Wie bringt man einen Computer – ob Desktop-PC, Webserver oder Smartphone – dazu, eine gewünschte Sequenz von Arbeitsschritten automatisch zu vollziehen? Das Buch erklärt Lesern, wie sich auch ohne Vorkenntnisse möglichst schnell erste Programme mithilfe objektorientierter Ansätze erstellen lassen. Benötigt wird dafür lediglich ein Computer mit Internet-Browser und Texteditor.Im Mittelpunkt des Buchs steht JavaScript, eine Programmiersprache, die in HTML-Dokumente eingebettet und dann im Browser ausgeführt wird. Besonderes Augenmerk legt der Autor auf die systematische Darstellung der Objektorientierung bei JavaScript. Die den Internetseiten zugrundeliegende Dokumentenbeschreibungssprache HTML wird nur soweit erläutert, wie es für das Verständnis der behandelten JavaScript-Thematiken notwendig ist. Sämtliche im Buch erläuterten Beispiele können auf der Homepage des Autors heruntergeladen werden.Das Buch vermittelt darüber hinaus Grundlagen zur Informationstechnologie und ihrer Geschichte – graphisch abgesetzt in Infoboxen oder in den Fußnoten. Diese Ausführungen laden zum vertiefenden Weiterlesen ein, können aber auch ausgelassen werden. So richtet sich der Band einerseits an Programmier-Einsteiger, die mit JavaScript und Web-Technologien arbeiten wollen, andererseits aber auch an Schüler und Studierende, die an Informatik-Einführungsveranstaltungen teilnehmen.Die zweite Auflage des Buchs trägt der rasanten Weiterentwicklung von JavaScript als Programmiersprache Rechnung. Zu den Neuerungen zählt beispielsweise die Spezifikation eines Befehls, mit dem Objekte einfacher und übersichtlicher deklariert werden können. Diese und andere wurden in die Neuauflage eingearbeitet.
