Julia - Begin

Julia introduced Compound expressions, which allow you to execute multiple expressions with a single value.

This can be achieved using begin and end keywords.

variable = begin
        expression1
        expression2
        expression3
    end

We can replace the above expressions into a single expression using the ; symbol.

variable = begin expression1; expression2; expression3; end

Here is an example

result = begin first = 2; second = 13; first * second end

Above Simplified using the below expression

(first = 1;
second = 2;
first * second)

Variable scope inside begin blocks.

The variables do not have any local scope until the local variable is declared.
