What is the difference between deferred and immediate execution?
An example of an AI chatbot conversation about deferred vs immediate execution in programming.
What is the difference between deferred and immediate execution?
Deferred execution means that the evaluation of an expression is delayed until its value is actually needed, while immediate execution evaluates the expression right away.
Can you give me an example of each?
Sure! In deferred execution, a query in LINQ might not run until you iterate over the results. In immediate execution, a method like ToList() forces the query to run immediately.
What are the benefits of using deferred execution?
Deferred execution can improve performance by reducing unnecessary computations and allowing for more efficient data processing.
Are there any downsides to deferred execution?
Yes, one downside is that it can lead to unexpected behavior if the data changes before the execution occurs, potentially causing stale data issues.
