	// -----Loops----- //

	/* For loops are great tools for iterating over individual elements within an array
	to work with them. A for loop has three sections within its proceeding parentheses: an
	initialization, conditional statement, and a final expression. The initialization phase
	usually declares a variable. The conditional statement phase tells the loop when to stop,
	and the final expression performs an action at the end, usually incrementing or
	decrementing a counter: */

	/* If statements are used in Javascript to make decisions--whether to execute a following

	console.log(typeof 10); // "typeof" is a unary operator

	/* Binary operators can be placed between two values and return a new value: */

	/* Undefined and null are both special values that signify the absence of meaningful
	data. Undefined is considered its own data type, but null is considered an object by Javascript,

	/* Functions are first-class objects, "subprograms" and reusable code that can be "called" or
	"invoked" at later times to produce a value or side-effect. To declare a simple function, first
	begin with the keyword "function" followed by the name, parentheses, and curly braces. The
	function body within the curly braces contains the sequence of statements to be executed when it

	// -----Objects----- //

	/* An object, like an array, is a container for data, but an object stores key/value pairs
	with curly braces. Almost every is considered an object except primitive values, including
	strings, numbers, booleans, null, and undefined. Objects can be created in three ways: */

BooleansBoolean studies// source http://jsbin.com/bameke

	// -----Data Types: BOOLEAN----- //

	/* A boolean is a data type that has one of two mutually
	exclusive values: true or false. A boolean acts like an "on-off"
	switch, where "true = on" and "false = off." They are used in
	conjunction with comparion operators to evaluate expressions.
	When comparing letters and non-alphnumeric characters, the
	character will resolve to its Unicode number, which will be
	used to make the comparison. When comparing strings, Javascript
	compares individual characters from left to right. */
