JavaScript

Hi, I am Surekha Madaan, a web designing student of ADMEC Multimedia Institute today I am writing a very easy and step by step tutorial on JavaScript for those who just started learning JavaScript or for beginners. This article is completely focused on JavaScript basics and contains useful information about the introduction of JavaScript, importance of JavaScript and how to write JavaScript programs etc. Besides explaining JavaScript, I will introduce the basic principles of programming and why language matters?

Use of typeof Operator in JavaScript

typeof checks for the datatype of a given value. Suppose you have a value in a variable or have multiple values in an array and you want to check the datatype or value type of that value then typeof operator is a solution in JavaScript.

I am giving an example of typeof operator here. In this example I have an array with numeric and string values and I want to take total of only numeric values.

Copy the following given JavaScript code and paste in your browser and save your file as ‘typeof.html’ and then publish in any of the browser and check the result.

In this JavaScript article I will elaborate a most common and less clear side of JavaScript i.e. 'what is the use of JavaScript in today's websites?'

This article will discuss value types or data types in javascript in detail. Type casting or data type conversion is also a part of this article.
