Can you give me examples of JavaScript array methods?

Can you give me examples of JavaScript array methods?

Sure! JavaScript has several array methods. For example, the map() method creates a new array by applying a function to each element of the original array.

Can you show me how to use the filter() method?

Absolutely! The filter() method creates a new array with all elements that pass the test implemented by the provided function. For instance:

const numbers = [1, 2, 3, 4, 5];
const evenNumbers = numbers.filter(num => num % 2 === 0);
console.log(evenNumbers); // Output: [2, 4]

What about the reduce() method?

The reduce() method executes a reducer function on each element of the array, resulting in a single output value. Here's an example:

const numbers = [1, 2, 3, 4];
const sum = numbers.reduce((accumulator, currentValue) => accumulator + currentValue, 0);
console.log(sum); // Output: 10
