What are the main disadvantages and problems of signals, especially when working with effects?

Signals are reactive primitives for tracking data changes. Main drawbacks and issues when working with effects:

• Implicit dependencies: Effects may depend on signals, but if dependencies are not explicitly specified, it can lead to bugs and hard-to-debug errors.
• Performance issues: Frequent updates to signals can cause unnecessary re-renders or repeated effect calls.
• Cyclic dependencies: If effects update signals that themselves trigger these effects, it can lead to infinite loops.
• Lack of control over execution order: In complex cases, it is difficult to guarantee the order of effect execution, which can lead to unpredictable behavior.

Example: if an effect is subscribed to a signal that is updated within the same effect, it can result in an infinite update cycle.
