Javascript is not a full programming language*. It is a complementary language that augments other processes like HTML and CSS. It was specifically designed for the Internet and every modern browser includes a Javascript interpreter.

Javascript is used to speed up web page loading, data verification and information displays. It does this by using your computer’s processor to execute its runtime operations.

To illustrate: there is no need to send detailed machine code instructions on how to paint the color red into a little box on your screen through the Internet. Your computer can already do all of this work by itself. Javascript operates on your computer to accomplish its work.

Javascript code for security reasons has strict limits that are designed to protect the web surfer. Because it operates on your computer processor this limitation is important and, the code is always public. The Javascript embedded in a web page is visible to anyone surfing the Internet.

WEBSOLUTIONS.TO can install Javascript code into an existing web page without conducting any sort of site pre-analysis. We do not need to see the architecture of a site to write Javascript.

*Javascript is related to and derived from JAVA, which is a full programming language.
