The Basics of Javascript

If you are writing big code it is very helpful write comments to the segment of the code as comment will not be executed, it is for codemasters to check where and which segment is located. Learning HTML is not the sole discretion of programmers as the trend can be seen it is been learnt by many bloggers and webmasters.

The sole purpose for this is to make it more and more convenience and to customize the web page to its fullest extent all by it self as with this knowledge in your kitty , you can reduce the cost factor as you can make the coding and with the advent of modern web technologies . With the advance modern web , where you can find more and more use of API and other related applications and with due course of time even the web page is fast becoming one of the conglomerate of applications visibility.

JavaScript is a scripting language and it is funnily called as diet programming language because of its easy in nature and the way it can be employed with very slight nature of use and appliances. It is been designed for easy to learn and adopt and it is wonderful for novices. It is also true that you can learn and can code the language within short span of time; it is very easy to use and adopt. It is a good practice to learn the basics of NTML before learning the basics of JavaScript. In the later time I shall write the details of HTML and the points which you should know about it.

How Java Script works:

Java and Java Script share the names only but these two languages have very little in common, in fact there are vast differences between these two languages. JavaScript is the language which meant to introduce the very basic elements of web and it is solely based in web and it works in cloud. Java is the language which tends to work as desktop application and in many big enterprises and also it goes on with to work online with various databases and its scope is very high and it does related with many applications and platforms simultaneously.

Java script is an interpreted languages and the browser interprets it and processed all the information in real time by contacting all server files and then interpret and shows it on your web page.  You can change the value of variables at any time s the name suggests it is dynamic in nature; all variables need a declaration – that is you have to tell the interpreter what to treat as variable.

Functions are blocks of code, once written can be used as many times as declared within the program. If you want to add the functionality of Add and Print, then you could write a function called AddAndPrint and so on. It is useful for more complex coding as it can supplement easily for hundreds lines of code and that can reduce the overall size of the code.

As JavaScript is always at the interpret side and works with browsers so minimization holds the key as if its size is very small then it would not affect the vital page load time and in this way you can have some of the added functionality plus search engine optimization and page rank settings. Many JavaScript in the web page can reduce the page load time, thus makes heavy the site and also it affects your site with Google Panda updates and for this it is vital in nature, as it can affect Google’s search front page.

That is why, it is good to use functions if you are using and coding long and in this manner it does makes the code small and precise. Object, in programs represent physical entitles, complete with their attributes and behaviours.  The objects you will encounter when writing Java Script code will include the browser window- you can use the command to open the window. Everything else is also an object- be it text boxes, images, even your mouse cursor.

Java Script code is always enclosed in the <script> tags inside your HTML document. You can insert code blocks anywhere in the document, but it is always good practice to enclose your script within the <head> tags of the HTML. This way, the script will always be loaded before it gets used within the page. There are no semicolons at the end of each line. They are purely optional, and there so that C programmers do not suddenly feel out of their elements when writing Java Script.

If you are writing big code it is very helpful write comments to the segment of the code as comment will not be executed, it is for code masters to check where and which segment is located. If you have the JavaScript code within your web page then in the modern browsers there are very vital functionalities from where the user can right click on the page and can see the view source to observe the use in your website. There are provisions while making the code if you do not want the visitors to watch the code then you can make it within <script> tags to employ this idea.

Variables in Java Script can be declared by using “var” statement. The switch statement takes the variable browser and compares it one by one to the values mentioned in the case statements. The break statement prevents the browser from executing the very next line of code and tells it to exit the switch block.

There is one different way you can check your conditions in Java Script- this one specifically if you want to assign a value to a variable based in a condition. Programming loops let you execute the same block of code over and over again as many times as you like. The simplest example would be printing the numbers 1 to 10 or 1 to 100. The for loop is typically used when you can predict exactly how many times a piece of code. The while loop effectively tells your browser as long as this condition is true keep executing this block of code. You would typically use a while loop to check a condition rather than execute code a specific number of times this reducing the page load times.
