Continue statement continues the current loop (if label not specified) in a new iteration whereas break statement exits the current loop.
In the context of web development interview questions, the correct answer to what break and continue statements do depends on the programming language being discussed, as they are common features in many programming languages. However, here’s a general explanation:
- Break Statement:
- In loops (such as for, while, or do-while loops), the
break
statement is used to terminate the loop prematurely. - When encountered, the
break
statement immediately exits the loop and continues with the code following the loop. - It’s often used when a certain condition is met within the loop, and you want to stop the loop execution.
- In loops (such as for, while, or do-while loops), the
- Continue Statement:
- The
continue
statement is also used within loops. - When encountered, it skips the rest of the code inside the loop for the current iteration and proceeds to the next iteration.
- It’s typically used when you want to skip some specific iterations of the loop based on certain conditions without terminating the loop entirely.
- The
These statements are particularly useful for controlling the flow of execution within loops, allowing developers to fine-tune how iterations are processed. In the context of web development, they can be used, for instance, to iterate through arrays, process data, or handle user interactions within a web application.
