What are some practical examples of using map, filter, and reduce in JavaScript?

Can you give me some practical examples of using map, filter, and reduce in JavaScript?

Sure! Let's start with map. It transforms each element in an array. For example, if you have an array of numbers and want to double each number, you can use map like this: const doubled = numbers.map(num => num * 2);

That makes sense! What about filter?

filter is used to create a new array with elements that pass a certain condition. For instance, if you want to get all even numbers from an array, you can do: const evens = numbers.filter(num => num % 2 === 0);

Great! And how does reduce work?

reduce is used to accumulate values in an array into a single result. For example, to sum all numbers in an array, you can use: const total = numbers.reduce((acc, num) => acc + num, 0);
