  11. Datatypes (Simple & Complex)
  12.  
  13. Ok lets start with Simple Data Types
  14. Simple Data Types Are Numbers, String, Boolean, Undefined, Null, and Nan.
  15. These particular data types are Primitive data types, they are atomic which are
  16. booleans, integers, characters and floats. Simple data types are also Immuatable
  17. which means they can bet changed. take note that they do not hold, collect, or
  18. aggregate other values. These data types are copy by value.
  19.  
  20. // so lets create a brief list on the definition of these data types:
  21.  
  22. Numbers consist of numeric data
  23. exp 1,2,3,4 etc
  24.  
  25. Strings consit of character data
  26. exp "hey liv updating studies"
  27.  
  28. Boolean consit of true or false
  29. exp var outStandingHuman = true
  30.  
  31. undefined consit of not having a value;
  32. exp var iHaveNoValue;
  33.  
  34. null is when you have variables that dosnt point to anything;
  35. exp var grace = "i am null";
  36. grace; "i am null";
  37.  
  38. NaN basicaly is the abreviation for not a number
  39. exp isNan("a"); this should tell you not a number
  40.  
  41. infinity: Thee is positive infinity and negative infinity. positive
  42. infinity is greater than any other number so negative infinity is less
  43. then any other number. Anything you add or multiply to infinity is infinity.
  44. Anything you subtract or divide from infinity is -infinity.
  45.  
  46. /*
  47. Complex Data Types
  48. Complex Data Types consist of Arrays, Objects, and functions
  49. Now these data types aggregate other values and are copy by reference.
  50. Another thing to note is that complex data types are indefinit in size.
  51.  
  52. // So lets give a brief definition of these data types
  53.  
  54. Arrays are a fixed size and operates on a numbered index system and our
  55. syntax for these arrays are bracket notation [].
  56.  
  57. Objects are collections of data which can hold pretty much every data type
  58. inside of our objects. Also these objects can expand indefintly in size)
  59.  
  60. Function: Functions are a set if statements that calculates values with blocks of code
  61. to be executed by invoking or calling a function. */
