Actually JavaScript and Espresso are extremely much unrelated. Java is certainly a complex programming language although JavaScript is only the server scripting language. The format involving JavaScript is typically motivated by the development language C.

Being the scripting language, JavaScript are not able to run on unique. Found in fact, the web browser is liable for running JavaScript code. Whenever a user requests a good HTML CODE page with JavaScript in it, the script is usually sent to this web browser and is particularly up to be able to the browser to carry out it.

You have for you to use the sort characteristic within just the
<script> tag make its value to text/javascript.
