Learning JavaScript

JavaScript is a programming language that allows you to implement complex things on web pages. This includes

  • Display static information for you to look at
  • Displaying timely content updates, or interactive maps, or animated 2D/3D graphics
  • Scrolling video jukeboxes, etc.

JavaScript is probably the third layer of the layer cake of standard web technologies, two of which (HTML and CSS).

Why JavaScript?

  • All browsers process JavaScript
  • Many web services rely on JavaScript in browser
  • JavaScript can be used in your own web pages
  • Understand what other web pages are doing
  • It is easy to start
  • It is easy to do useful things with it
  • In JavaScript programming ideas carry over into other languages


We will describe basic syntactic principles of JavaScript.


Note the two different uses of the equals sign:

  • A single equals sign (=) is used to assign a value to a variable.
  • A triple equals sign (===) is used to compare two values (see Equality Operators).
