You will need to know some information about JavaScript if you plan to write it and throughout this article you may find any affiliated information about it. First off, writing JavaScript needs tools and the first tool is a plain text editor. For example, you can use notepad if you use Windows and Simpletext if you use Mac, whereas Linux offers you a number of selections of plain text editors and you can pick the one you desire installed in your computer system.

However, you can have other fancier than a plain text editor if you like, only by take a closer look to the options provided in your web editor you will be able to find the selections to enter JavaScript as well as HTML as plain text. Through the one you have chosen, you can write and edit the JavaScript, also it benefits you since the editor can probably recognize JavaScript and has the ability to color code the JavaScript which you write using different colors to show JavaScript keywords.

Actually, you can have another type of program to write your own JavaScript which is the web browsers that can test them in. It means, you can use not only any version of Internet Explorer that usually came preinstalled on the Windows OS or Safari which also came preinstalled on your Mac, you can use three different web browsers.

Furthermore, the web browsers that are usually used divided into four groups. In details, Internet Explorer is used on Trident rendering engine, whereas Firefox, Netscape, and Mozilla are built on the Gecko rendering engine. Other groups are opera that is used on the Presto rendering engine and Safari and Konqueror that are built on KHTML rendering engine.

You should notice that browsers that use a different rendering engine can behave inversely although the process uses the same code. Therefore, the ideal minimum setup to test the web pages is to test particular browser that uses each of the four different rendering engines. But the obstacles appear especially learning that you can only use three different rendering engines instead of four.

The explanation is that when you can test with all four on Windows Operating System which is obviously supporting Internet Explorer, Opera, Firefox, and Safari, it is an unfortunate that you will not be able for you to use a Mac or Linux. After you use the browsers to ensure that your JavaScript works, you then make necessary changes to the code. It is important for you to test your scripts carefully before uploading it to your website.
