What are some native array methods in JavaScript?

JavaScript provides several native array methods like map, filter, and reduce. Would you like to know how to use any of them?

Can you explain how the map method works?

Sure! The map method creates a new array populated with the results of calling a provided function on every element in the calling array.

Can you give me an example of using the filter method?

Absolutely! The filter method creates a new array with all elements that pass the test implemented by the provided function. For example, array.filter(num => num > 10) returns all numbers greater than 10.

What about the reduce method?

The reduce method executes a reducer function on each element of the array, resulting in a single output value. For instance, array.reduce((acc, curr) => acc + curr, 0) sums all elements.
