FaJa id fully object oriented and dynamically typed programming language.
Every class start with keyword class and ends with endClass. Object is singleton class => there is only one instance. Class or Object can extend another class using extends keyword. Class can contains fields and methods. Fields definition starts with fields keyword. Fields can be separated by comma or new line. Fields section ends with endFields keyword. Methods starts with methods and ends with endMethods keyword. One line comments starts with :-)
Each method starts with def keyword and ends with end keyword. After def follow method name and in branches there are arguments separated by comma. Local variables are defined using keyword var. This class fields or methods can be access using keyword self:. Method call is performed by comma. You can also assign come method result or literal or another variable to some variable using <- operator.
Closure body start with { and ends with }. After start bracket can be comma separated arguments list. Arguments block ends with |. Closure body can be same as method body.
String literal is everything between " and ".
Number literal is only number.
Null literal is null.
Bool literals are true and false.
Array literal is [].
