An example of an AI chatbot conversation about using map, filter, and reduce in JavaScript.
How can I use map, filter, and reduce in JavaScript?
You can use map to transform arrays, filter to select elements, and reduce to accumulate values. Would you like examples?
Yes, please provide examples for each.
Sure! For map: const doubled = arr.map(x => x * 2); For filter: const evens = arr.filter(x => x % 2 === 0); For reduce: const sum = arr.reduce((acc, x) => acc + x, 0);
Can you explain how reduce works in more detail?
Absolutely! Reduce takes a callback function and an initial value. It processes each element, accumulating a result.
