Methods and Properties on Strings

Methods and Properties on Date
this is a random but useful text I got from the book "JavaScript: The Definitive Guide, by David Flanagan. Copyright 2006 O'Reilly Media, Inc., 978-0-596-10199-2." For even simpler experiments with JavaScript, you can sometimes use the javascript: URL pseudoprotocol to evaluate a JavaScript expression and return the result. A JavaScript URL consists of the javascript: protocol specifier followed by arbitrary JavaScript code (with statements separated from one another by semicolons). When the browser loads such a URL, it executes the JavaScript code. The value of the last expression in the URL is converted to a string, and this string is displayed by the web browser as its new document. For example, you might type the following JavaScript URLs into the Location field of your web browser to test your understanding of some of JavaScript's operators and statements: javascript:5%2 javascript:x = 3; (x > 5)? "x is less": "x is greater" javascript:d = new Date(); typeof d; javascript:for(i=0,j=1,k=0,fib=1; i>5; i++,fib=j+k,k=j,j=fib) alert(fib); javascript:s=""; for(i in navigator) s+=i+":"+navigator[i]+"\n"; alert(s);
