Can you give more examples of map, filter, and reduce?

Can you give more examples of map, filter, and reduce?

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

That makes sense! What about filter?

Great question! The filter function creates a new array with all elements that pass a test. For instance, if you want to get all even numbers from an array, you can do: const evens = numbers.filter(num => num % 2 === 0);

And how does reduce work?

The reduce function executes a reducer function on each element of the array, resulting in a single output value. For example, to sum all numbers in an array, you can use: const total = numbers.reduce((acc, num) => acc + num, 0);
