What is the standard language specification that JavaScript is based on?What datatypes does JavaScript support? Is JavaScript strongly typed or loosely typed? Explain the difference.What is the value for each of the following variables after the code is executed?var i = "She swam " + 10 + " laps.";var j = 10 + "5";var k = 10 – "5";var l = 10 * "5";var m = Number("152");var n = parseInt("0 dogs");var b;if (n) {b = true;} else {b = false;}Can JavaScript code executed in the Web browser access the computer’s filesystem? Explain.

A composite-metaphor interface is a computer interface consisting of a combination of two or more metaphors. As computer systems have become more sophisticated, researchers have proposed the use of multiple metaphors to design computer systems because they would better match the characteristics of complex target systems; however, due to the difficulty of designing interface metaphors and limited research in this area, there are few guidelines or accepted standards for generating and implementing composite metaphors for interface design. In this paper, the authors propose an approach for designing composite metaphors. We first present the metaphor design strategies as we interviewed eight game designers, then summarize the design considerations from the metaphor literatures. Please search in EBSCO for the following article.  EBSCO is located under the Resources tab at the top of the page.  Then carefully read the article and respond to the discussion forum question posted.  Blair-Early, A., & Zender, M. (2008). User Interface Design Principles for Interaction Design. Design Issues, 24(3), 85-107.  NOTE: To access full text of the article click on “PDF Full Text.” The author proposes the design approach for selecting and combining metaphors in designing composite-metaphor interfaces. Discuss the advantages and disadvantages to author’s approaches. What suggestions would you provide to improve the author’s design approach?
