JavaScript for Beginners: Introduction

• What is JavaScript?
  Javascript is a compact object based client-side scripting language designed for the web. It has nothing to do with "Java", but was named Javascript for marketing purposes. The code is embedded and integrated into HTML on the user's browser. Data types are "loose", and not necessarily declared.
• Who invented JavaScript?
  Javascript was developed by Netscape and Sun Microsystems
• What can JavaScript do?
  Javascript is only a scripting language. Scripting languages are hybrids of markup languages and some programming.
• What can JavaScript not do?
  Javascript does not have access to the user's computer. It cannot even write or read to the user's hard disk except to access "cookies."
• How do you activate JavaScript?
  Javascript is activated within HTML container tags: <SCRIPT>. Execution of the scripts can either be immediate (by placing the script within the Header), or deferred.
