Q&A: What exactly is Javascript?

Question by Muyarna: What exactly is Javascript?
I know it’s a programming language, but is it like another version of HTML code? I heard you can use it on Dreamweaver, which I own, so how do I use Javascript? Do I have to practice all that Javascript stuff? Like, I don’t get how to import it into a website, and I don’t know what Javascript exactly DOES. What is it used for specifically? And I know it makes “programs” – what kind of programs? Like, forms with submit buttons? Like you do on Dreamweaver? What exactly is Javascript useful for? And how can I use it in Dreamweaver? I’ve done Actionscript on Flash, which I heard is almost exactly like Javascript, but it still confused me. And I must be confusing you. Hooray.

    JavaScript is a scripting language used to enable programmatic access to objects within other applications. It is primarily used in the form of client-side JavaScript for the development of dynamic websites. JavaScript is a dialect of the ECMAScript standard and is characterized as a dynamic, weakly typed, prototype-based language with first-class functions. JavaScript was influenced by many languages and was designed to look like Java, but to be easier for non-programmers to work with.”

    hey……java script is a client side scripting language. Say you want to check when some logged in to your web site whether he/she has entered correct userName and password. If these validations are check on the client side, then it can reduce load on server for which server side scripting languages are used.

    Javascript is nothing but it is used to perform validation on forms when someone create account on your site like password and Re-Enter password field should match, Age should be greater than 18 like these kind of validation if you want to check on our forms.

    Dreamweaver is a tool for used for coding. In this you don’t have to remember function name, when u write first letter it will show you list of functions, these kind of features are there.It is better to use it for coding.

    And the most important You can start learning javascript from http://www.W3schools.com. Very wll explained.

    Thinking of developing a webSite without using Javascript is of no use, so better to use it.

    All d best……..
