What are some common JavaScript array methods?

Some common JavaScript array methods include push, pop, shift, unshift, map, filter, and reduce. Would you like to know more about any specific method?

Can you explain how the map method works?

Sure! The map method creates a new array by applying a function to each element of the original array. For example, if you have an array of numbers and you want to double each number, you can use map to achieve that.

What about the filter method?

The filter method creates a new array containing all elements that pass a test implemented by the provided function. For instance, if you want to get all even numbers from an array, you can use filter.

Can you give me an example of using reduce?

Absolutely! The reduce method executes a reducer function on each element of the array, resulting in a single output value. For example, you can use reduce to sum all numbers in an array.
