Java vs javascript (XPages)
Download as pptx, pdf0 likes1,530 views
The document compares Java and JavaScript, noting that while both are important for developing applications, they serve different purposes. For end users, the technology is irrelevant as long as the application works well. For developers, JavaScript may be better to learn first as it allows for elegant user experiences, while Java enables more capabilities. For management, the skills of their current team should be considered to determine which language to use. The document provides examples of companies that used JavaScript or Java for their projects based on these considerations. It concludes that while JavaScript is often sufficient, developers should learn Java to expand their skills.
