| 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.

| - | ==== Tables ==== | + | ===== Tables |
| As in Pico, indexed tables represent what other languages call arrays or lists. Tables are unidimensional and their indexes range from 1 to the size of the table. As variables, one can define, assign and refer to a table.
