How do different array methods compare in JavaScript?

Can you explain the differences between map, forEach, and filter in JavaScript?

Sure! The map method creates a new array by applying a function to each element, while forEach executes a function on each element without returning a new array. filter, on the other hand, creates a new array with elements that pass a test defined by a function.

When should I use filter instead of map?

Use filter when you want to create a subset of an array based on a condition. Use map when you want to transform each element of the array.

Can you give me an example of using these methods?

Of course! For map, you might use it to double each number in an array. For filter, you could use it to get all even numbers from an array.

What about reduce? How does it fit in?

reduce is used to accumulate values from an array into a single result, like summing all numbers or concatenating strings.
