A value, the data assigned to a variable, may contain any sort of data. Though, JavaScript considers data to fall into many possible types. Based on the type of data, certain operations may or may not be allowed on the values. For instance, you cannot multiply arithmetically two string values. Variables can be of following types:
Data Types
Description
Number
3 or 7.987 are the examples of Integer & floating-point numbers.
Integers can be positive, 0, or negative; Integers can be expressed in decimal (base 10), hexadecimal (base 16), and octal (base 8). A decimal integer literal contains a sequence of digits without a leading 0 (zero). A leading 0 (zero) onto an integer literal denote it is in octal; a leading 0x (or 0X) specified hexadecimal. Hexadecimal integers can include digits (0-9) and the letters a-f & A-F. Octal integers can include only the digits 0-7.
A floating-point number can contain either a decimal fraction, an "e" (uppercase or lowercase), that is used to represent "ten to the power of" in scientific notation, or both. The exponent part is an "e" or "E" followed by an integer, which can be signed (preceded by "+" or "-"). A floating-point literal ought to have at least one digit & either a decimal point or "e" (or "E").
Boolean
True or False. The possible Boolean values are true & false. These are special values, & not usable as 1 & 0. In a comparison, any expression which evaluates to zero is taken to be false, & any statement which evaluates to a number other than 0 is taken to be true.
String
"Hello World!" Strings are delineated through single or double quotation marks. (Employ single quotes to type strings that have quotation marks.)
Object
MyObj = new Object();
Null
Not the simialr as zero - no value at all. A null value is one which has no value and means nothing.
Undefined
A value which is undefined is a value held through a variable after it has been created, however before a value has been assigned to it.
