Scala is both object-oriented and functional programming language by Martin Odersky in the year 2003.
Variable is a name given to the storage area in order to identify them in our programs.
If, If-else, Nested-Ifs are used when you want to perform a certain set of operations based on conditional expressions.
For loop is used to iterate a set of statements based on a criteria.
While is also used to iterate a set of statements based on a condition. Usually while is preferred when number of iterations are not known in advance.
Do-while is also used to iterate a set of statements based on a condition. It is mostly used when you need to execute the statements atleast once.
Function is a sub-routine which contains set of statements. Usually functions are written when multiple calls are required to same set of statements which increases re-usuability and modularity.
You can either use = or not in the function definition. If = is not present, function will not return any value.
