Julia introduced Compound expressions, which allows you to execute multipl expressions with a single value.
This can be acheived using
variable = begin expression1 expression2 expression3 end
We can replace the above expressions into a single expression using
variable = begin expression1; expression2; expression3; end
Here is an example
result = begin first = 2; second = 13; first * second end
Above Simplified using below expression
(first = 1; second = 2; first * second)
Variable scope inside begin blocks.
The variables does not have any local scope until local variable is declared.
