Javascript For Loop Code Syntax Example
posted byshawpnenduinDevelopment
Loops are the most common and complicated part of any programming language. First of all what is loop or iteration? Loop is used for executing a set of statements or instructions repeatedly. To perform the repetitive task, Javascript provides us 3 types of Loop. For Loop is one of them. In this free javascript tutorial i am going to discuss on only For Loop. If we need to run multiple statement within a loop then the statements must be enclosed by curly braces { }. But for a single statement no need to wrap the line within curly braces because, for any iteration/loop if the condition satisfy then by default first line of code will be executed. This statement is also true for other programming languages. Keep in mind two things when you want to write a loop statement:
1. Statements that you need to iterate
2. Termination or exit from loop

Getting started tutorial on building Apps for mobile devices using web technologies
posted byreconninDevelopment
PhoneGap is a free open source framework which gives you access to native APIs. I’m working on a Windows station, but this can also be done on Linux and OSX. The main advantage to using web technologies with PhoneGap is that web designers and web developers can write HTML5, CSS and JavaScript code and still be able to build Apps for mobile devices without having to learn other programming languages such as C++, Objective C or JAVA. The best part is that you write code once and build for Android, iPhone, Blackberry, Windows Phone, WebOS, Symbian.
