Can you explain how they differ from regular functions in terms of performance?

MagicBuddy

Sure! Arrow functions do not have their own 'this' context, which can lead to performance benefits in certain scenarios, especially in callbacks.

Are there any situations where using arrow functions might be less efficient?

MagicBuddy
MagicBuddy

Yes, in cases where you need to use 'this' context or when creating methods in classes, regular functions might be more efficient.

Arrow functions can lead to increased memory usage if they are created in loops, as each iteration creates a new function instance.
