This part of the tutorial shows AmbientTalk as a simple expression language with a minimum syntax which resembles very on Java script. This section mainly describes the basic features of the language, namely variables, functions and tables and control flow. | This part of the tutorial shows AmbientTalk as a simple expression language with a minimum syntax which resembles very on Java script.

- | ==== Variables ==== | + | ===== Variables |
As usual, one can define, assign and refer to a variable. Variable definitions are made with the keyword **def**. Note that AmbientTalk is a dynamically typed language so, variables do not have a type but, they just contain values. | As usual, one can define, assign and refer to a variable.

- | Although there is no special constructor for definition of multidimensional tables, a table entry can contain another table. This is internally stored as a unidimensional table whose entries are other tables. | ||
