The use of Javascript
As what the w3schools.com said, JavaScript is used in millions of Web pages to improve the design, validate forms, detect browsers, create cookies. However, there is some web applications use javascript to verify the user input in client-side but not no more checking in server-side. It is very dangerous that some hackers may modify the page to skip the javascript checking and submit some unwanted data to the server.Before we learn the syntax of a programming language, we should studay the properties of this language. Other the w3schools.com, I've found some other sites which is useful for learning javascript.
