You define variables by simply assigning a value to them. They do not need to be declared. However, you can use the var statement to explicitly declare a variable.
Variable names are not case sensitive. Variable names must begin with a letter or underscore, not a digit.
All variables are string variables. There are no types like in C, and no need to declare variables. This makes working with variables very easy. There is no need to do conversions or casts. In addition, there is no need for string memory management.
