What are circular references and can you give me some examples?

Circular references occur when two or more resources reference each other, creating a loop. For example, in programming, if Object A references Object B, and Object B references Object A, that's a circular reference.

Can you explain why circular references can be problematic?

Yes, circular references can lead to memory leaks and make it difficult for garbage collectors to free up memory, as the objects remain reachable.

Are there any programming languages that handle circular references better than others?

Some languages, like Python, have built-in garbage collection that can handle circular references, while others may require manual management.

Can you provide a code example of a circular reference?

Sure! Here's a simple example in JavaScript:

function A() {
    this.b = new B();
}

function B() {
    this.a = new A();
}

let a = new A();
