This tutorial looks at touch related events in JavaScript and how they are used to detect and respond to touch and swipe events. With touch based devices ever growing in numbers, grasping touch related events in JavaScript is as essential as understanding the age old mouse events.

For a Javascript beginner, understanding the “if else” conditional statement is very much important. Its impossible to write conditional statement without “if else”, so read the article carefully. In this lesson i will try to give you a complete understanding on “if else” conditional statement to build up your desire logic. Keep in mind that the “if” code block will be executed if the underlying condition return TRUE value. If return false value then “else” code block will be executed. So lets start to learn the most common Javascript “if else if” code syntax.

To build a logic most of the times we need to use AND, OR, NOT operators in our conditional statements. Javascript also provide us all AND, OR, NOT operators. Since different programming language has different AND, OR, NOT syntax, sometimes we forget the language specific code syntax. This article or javascript lesson provide you the code syntax or example of the above three operators.

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
