What are some examples of array methods in JavaScript?

JavaScript has several array methods like map, filter, and reduce. Would you like examples of each?

Yes, please provide examples for map and filter.

Sure! For map, you can use it to create a new array by applying a function to each element. For example: const doubled = arr.map(x => x * 2); For filter, it creates a new array with elements that pass a test: const evens = arr.filter(x => x % 2 === 0);

Can you explain how reduce works?

Absolutely! The reduce method executes a reducer function on each element of the array, resulting in a single output value. For example: const sum = arr.reduce((acc, curr) => acc + curr, 0); This sums all elements in the array.
