The name of the variable is always supplied by the programmer and cannot contain spaces.
Variables can hold text data, numerical data, true / false (boolean) data or object data which could refer to a specific row in a database table or a chunk of HTML code.
Variables are assigned values with the assignment operator =. In every case the right side of the assignment operator is the value being assigned and the left side is the name of the variable it is being assigned to.
Now open the variables and assignment exercise and work through it.
