What are some alternatives to the reduce function in JavaScript?

What are some alternatives to the reduce function in JavaScript?

You can use methods like forEach, map, or a simple for loop to achieve similar results as reduce.

Can you give me an example using forEach?

Sure! You can accumulate values in an array using forEach like this: let sum = 0; arr.forEach(num => sum += num);

What about using map? How does that work?

Map creates a new array by applying a function to each element. You can then use reduce on that new array if needed.

Are there any performance differences between these methods?

Yes, performance can vary. For large datasets, reduce might be more efficient, but it depends on the specific use case.
