Booleans Derive their name from George Boole, the 19th century logician who developed the true/false system of logic upon which digital circuits would later be based. With this in mind, it should come as no surprise that Booleans take on one of two values. true or false .      Comparison expressions such as a<y evaluate to a Boolean value depending  upon whether the comparison is true or false . so the condition of a control structure such as if/else is evaluated to a Boolean to determine  what code to execute.  For example:  if(a==y) {   a=a+1; }     increments a by 1 if the comparison a equal to y is  true. you can use booleans explicitly to the same effect, as in var doIncrement = true; if(doIncrement)  { a=a+1; }   or  if(true) { a=a+1; }  Booleans are commonly included as object properties indicating an  on/off state. For example, the cookieEnabled properties o...

f unction are used to encapsulate code that performs a specific task. Sometimes functions are defined for commonly required tasks to avoid the repetition entailed in typing the same statements over and over . More generally, they are used to keep code that performs a particular job in one place  in one order to enhance reusability and program clarity.           JavaScript function are declared with the function keywords, and the statements that carry out their operations are listed in curly braces. Function  arguments are listed in parentheses following the function name and are separated  by commas.   For example: function add (a, b) { var sum =  a+b; return sum; } This code declares a function named  add  that adds its argument  together and  "returns"    the resulting value. The return statement tells the interpreter what value the function evaluates to. For example, you can set th...
