Lazy Evaluation

Question

Hello Everyone. 

I have a little question abuot the Chora Language : does it use Lazy Evaluation?
For example, in a code snippet like the following :

var bool A = false;
if(A && foo() )
{
  ... something something ...
}

will foo() be called?

Answer 1

Hello,

in this case (with variable A being false) the expression foo() right to the && operator is not evaluated. The method is thus not invoked. The logical operators && and || stop the evaluation as soon as the result of the expression is determined. In this case the value false in operand A affects the entire expression to return false.

I hope it helps you further.

It is important to add, that the evaluation is performed from left to right. That means in case of ( foo() && A ), the method foo() is invoked even if A is false.
