Javascript build-in global object reference.

Syntax:	decodeURI(URI)
	Decodes a URI which has been encoded with encodeURI. Is primarily intended for use with query string that is added to a Web address to make sure it is not misinterpreted as some of the other parts of the address.
Return value:	A decoded string
URI:	URI string to be decoded.
An example of using the decodeURI() :

Infinity :	A numeric value that represents positive infinity.
NaN :	The not-a-number value.
undefined :	The undefined value. Appear for a variable that has been declared but never had a value assigned to it or any value type that does not exist.

Syntax:	encodeURI(URI)
	Encodes a URI. ASCII letters and digits including the characters - _ . ! ~ * ' ( ) ; / ? : @ & = + $ , # are not encoded. Is primarily intended for use with query string that is added to a Web address to make sure it is not misinterpreted as some of the other parts of the address.
Return value:	A encoded string
URI:	URI string to be encoded.
An example of using the encodeURI() :

Syntax:	encodeURIComponent(URI)
	Encodes a URI. ASCII letters and digits including the characters - _ . ! ~ * ' ( ) are not encoded. Is primarily intended for use with web search query for which parameter values need special encoding and decoding.
Return value:	A encoded string
URI:	URI string to be encoded.
An example of using the encodeURIComponent() :

Syntax:	escape(string)
	Computes a new version of a string value in which certain characters have been replaced by a hexadecimal escape sequence. For those characters being replaced whose code point value is 0xFF or less, a two-digit escape sequence of the form %xx is used. For those characters being replaced whose code point value is greater than 0xFF, a four-digit escape sequence of the form %uxxxx is used
Return value:	A string including escape sequence.
string:	A string to be computed
An example of using the escape() :

Syntax:	eval(strEx)
	Evaluates a string of JavaScript code in the current lexical scope.
Return value:	The value of the evaluated code, if it exists. undefined, hvis strEx ikke returnere noen verdi eller uendret strEx hvis det ikke er en streng.
strEx:	A JavaScript string expression to be evaluated or a statement to be executed.
An example of using the eval() :

Syntax:	isFinite(number)
	Tests whether a value is a finite number. Returns false if the test is NaN, +∞, or -∞, and otherwise returns true.
Return value:	A boolean value
number:	The number to test.
An example of using the isFinite() :

Syntax:	decodeURIComponent(URI)
	Decodes a URI which has been encoded with encodeURIComponent. Is primarily intended for use with web search query for which parameter values need special encoding and decoding.
Return value:	A decoded string
URI:	URI string to be decoded.
An example of using the decodeURIComponent() :

Syntax:	isNaN(number)
	Tests whether a value is the not-a-number value. Will with the test returns true if the result is NaN, and otherwise returns false.
Return value:	A boolean value.
number:	The number to test.
An example of using the isNaN() :

Syntax:	parseFloat(string)
	Produces a number value dictated by interpretation of the contents of the string argument as a decimal literal.
Return value:	A float value or NaN if the string is not possible to parse.
string:	A string to be parsed. Interpret only a leading portion of the string as a number value.
An example of using the parseFloat() :

Syntax:	parseInt(string , radix)
	Produces an integer value dictated by interpretation of the contents of the string argument according to the specified radix.
Return value:	Parsed value or NaN if the radix is less than 2 or greater than 36.
string:	The string to be parsed. Leading whitespace in the string is ignored. An option minus sign in the start is allowed.
radix:	If radix is undefined or 0, it is assumed to be 10. When radix begins with the character pairs 0x or 0X, a radix of 16 is assumed. If this argument is less than 2 or greater than 36, the function returns NaN.
An example of using the parseInt() :

Syntax:	unescape(string)
	Computes a new version of a string value in which each escape sequence of the sort that might be introduced by the escape function is replaced with the character that it represents.
Return value:	A computed string where escape sequences are replaced.
string:	A string to be computed
An example of using the unescape() :
