What are nested comments?
A nested comment is a comment inside another comment. In Java you can’t nest a multiline comment into another multiline comment, however you can nest a single line comment into a multiline comment (but does this make sense?) /* This is a comment // this is a nested comment This is another comment */
Why does C not allow nested comments?
Because C’s comments start and end with specific characters, you cannot put one comment inside another. This is known as nesting. Nested comments can cause errors in your code, so while you’re programming, keep track of where comments start and end. That’s the part the compiler ignores as a comment.
Can comments in Java be nested?
Nested comments is not natively a feature of java. So what can you do? Here are some different options: Slash Slash comment nesting The best I’ve been able to come up with is to use an editor that has a hotkey to slashslash comment out an entire block of code as //’s can be nested.
How does a nested comment work in react?
It takes a parent comment object for a parameter and maps () each of the parent’s children comments. When it’s done, it stores the results in an array of components nested inside each other called nestedComments.
Which is an example of the use of recursion?
A great example of where recursion can be put into practice is a comments section on a website like Reddit or Hacker News. Each parent comment has one or more children comments nested below them. And each of those children’s comments can have one or more children of their own.
How to recursively render Parent Comments in react?
Here’s a function that will recursively render each parent comment and its children: This is a function we would place inside a React component and have it render each parent comment that is stored in our data. It takes a parent comment object for a parameter and maps () each of the parent’s children comments.
What do you need to know about recursion in react?
Before we jump into a React use-case for recursion, it will help to have a good understanding of what recursion is in the realm of computer science. Recursion is a technique for solving a problem where the final solution depends on several solutions to smaller instances of the same problem.
