When should I use reduce in JavaScript?

Can you explain when to use the reduce method in JavaScript?

Sure! The reduce method is used to execute a reducer function on each element of an array, resulting in a single output value.

What kind of problems is reduce best suited for?

It's great for aggregating data, like summing numbers, flattening arrays, or transforming data structures.

Can you give me an example of using reduce?

Absolutely! For instance, you can use reduce to sum an array of numbers like this: const sum = numbers.reduce((acc, curr) => acc + curr, 0);.

Are there any performance considerations when using reduce?

Yes, while reduce is powerful, it can be less performant than for loops for large datasets due to function call overhead.
