Introduction to JavaScript

• JavaScript is a scripting programming language used to enhance webpages and provide user interaction
• JavaScript and the Java programming language are not the same, although they are both based on C syntax
• JavaScript cannot run on its own and requires a host program such as a web browser in order to run
• JavaScript and HTML work hand-in-hand to perform tasks and display text and graphics
• A programmer can place comments after a double slash (“//”) within JavaScript code
• There are three basic ways to view JavaScript:
• As a webpage through a browser
• As read-only source code through the browser
• As editable code in text editor
