Category	Subject	Sinopsys	Description	Example
Function	escape(string)	escape(string) method converts the special characters like space, colon etc of the given string in to escape sequences	escape("test val"); -> return: "test%20val"
Function	unescape(string)	unescape(string); function replaces the escape sequences with original values. %20 is the escape sequence for space " "	unescape("test%20val");
Function	eval(string)	Evaluates a string of JavaScript code in the context of the specified object
Function	isFinite(x)	Determines whether a number is finite. Returns false if x is +infinity, -infinity, or NaN
Function	isNaN(testValue)	The isNaN function evaluates an argument to determine if it is 'NaN' (not a number)	isNaN(23); -> return: false
Function	Number(obj)	Converts the specified object to a number
Function	parseFloat(string)	parseFloat parses its argument, the string str, and attempts to return a floating-point number. If it encounters a character other than a sign (+ or -), a numeral (0-9), a decimal point, or an exponent, then it returns the value up to that point and ignores that character and all succeeding characters. If the first character cannot be converted to a number, it returns 'NaN' (not a number).
Function	parseInt(string[, radix])	parseInt parses its first argument, the string str, and attempts to return an integer of the specified radix (base), indicated by the second, optional argument, radix. For example, a radix of ten indicates to convert to a decimal number, eight octal, sixteen hexadecimal, and so on. For radixes above ten, the letters of the alphabet indicate numerals greater than nine. For example, for hexadecimal numbers (base 16), A through F are used. If parseInt encounters a character that is not a numeral in the specified radix, it ignores it and all succeeding characters and returns the integer value parsed up to that point. If the first character cannot be converted to a number in the specified radix, it returns 'NaN'. The parseInt function truncates numbers to integer values
Function	String(obj)	Converts the specified object to a string
Property	Infinity	Infinity is a global property (variable) with a constant value. If the result of a mathematical calculation would result in a number that is to big to be held in a Javascript numeric field then this value is assigned to the field instead
Property	NaN	NaN is a global property (variable) with a constant value. NaN is an abbreviation for 'Not a Number'.
Property	undefined	undefined is a global property (variable) with a constant value. Javascript treats undefined as being equal to null
Function	decodeURI()
Function	decodeURIComponent()
Function	encodeURI()	Used to encode the full URI, not including any parameters added to it , for special characters
Function	encodeURIComponent()
