For storing values you have to declare a variable, for that the keyword var is used. There is no need to specify the data type.

Syntax:

var <variable name1> [,<variable name2> ,<variable name3> ,etc…]

Here square bracket indicates optional.

Eg: var x, y, z;

x= 11;

y = ”BVM”;

z = false;

Here x is of number type, y is of string and z is of Boolean type.
