Introduction To JavaScript  in Simple Words 

JavaScript is a computer language that helps websites become more interactive and dynamic. It’s like the glue that holds web pages together. Whenever someone visit a webpage and click on buttons, fill out forms, or see animations its All About JavaScript. It can do things like change the content on a page without needing to reload it, make pop-up messages, and even remember information you’ve entered. In a nutshell, JavaScript makes websites feel alive and responsive, allowing you to do more than just look at static information

  • a lightweight programming language (“scripting language”)
  • used to make web pages interactive
  • insert dynamic text into HTML (ex: user name)
  • react to events (ex: page load user click)
  • get information about a user’s computer (ex: browser type)
  • perform calculations on user’s computer (ex: form validation)

JavaScript VS Java 

  • interpreted, not compiled
  • more relaxed syntax and rules
  • fewer and “looser” data types
  • variables don’t need to be declared
  • errors often silent (few exceptions)
  • key construct is the function rather than the class
  • “first-class” functions are used in many situations
  • contained within a web page and integrates with its HTML/CSS content
