When should I use reduce instead of map or filter?
An example of an AI chatbot conversation about when to use reduce instead of map or filter.
Can you explain when to use reduce instead of map or filter?
Sure! Use reduce when you want to accumulate a single result from an array, while map and filter return arrays.
Can you give me an example of using reduce?
Absolutely! If you want to sum all numbers in an array, you can use reduce like this: array.reduce((acc, curr) => acc + curr, 0);.
What about map and filter? When should I use those?
Use map to transform each element in an array and filter to create a new array with elements that pass a test.
Thanks! So, reduce is for single results, while map and filter are for arrays?
Exactly! You've got it!
