  • 1. By: Priyanka zope
  • 2. About CoffeeSCript • The Golden Rule: o "Its just JavaScript" • One-to-One Compilage into equivalent JavaScript • Runs as fast or faster than equivalent JavaScript
  • 3. The code writing and use process of CoffeeScript is simple: Write your code in a .coffee file Compile it into a .js file Include the .js file in your web page/s like you would any other JavaScript file
  • 4. COMMAND THROUGH coffee --watch --compile try.coffee DIRECT IN HTML FILE <script src="https://jashkenas.github.com/coffee- script/extras/coffee-script.js" type="text/javascript"></script>
  • 5. Variables Functions Arrays Conditional Operator Switch Statment
  • 6. Variables There is no need to declare variable in cofeescript. For e.g.: **javascript** var message; message=“ready for some cofeescript” alert(message); **coffeescript** message=“ready for some cofeescript” alert(message)
  • 7. Function • White Space Delimiter o Semicolons ';' are useless • Curly braces '{}' are unnecessary o Solved with indents or new lines • Functions o () contains parameter list o -> points to the body
  • 8. Array Arrays can use whitespace instead of comma separators, although the square brackets ([]) are still required. array1 = [1, 2, 3] array2 = [ 1 2 3 ]
  • 9. Conditional Operators Existential Operator • In JS, "if (var)" is close o Fails on 0, "", and false • In CoffeeScript o "?" returns true if null or undefined
  • 10. Switch Statements • Typical Switch has o Switch cond: o case 1, break; case 2, break; ...... • Switch in CoffeeScript o Switch cond:  when ... then ... else o does not require "breaks" or "default"
