The dialect was initially identified as LiveScript and has been later renamed JavaScript. There are several programmers who assume that JavaScript and Java are the same. Actually JavaScript and Espresso are really much unrelated. Java is a very complex programming language whilst JavaScript is only some sort of server scripting language. The syntax regarding JavaScript is mainly affected by the coding language C.

Being the scripting language, JavaScript cannot run on unique. Inside fact, the visitor accounts for running JavaScript code. If a new user requests a HTML CODE page with JavaScript in it, the script is sent to often the web browser and is particularly up to the browser to perform it.
