Topic Overview and Actualization

Welcome to this interesting lesson! We're going to explore JavaScript array methods, specifically: forEach(), map(), filter(), reduce(), and find().

Understanding the Role of Array Methods

JavaScript arrays can store multiple values. Array methods enable us to perform operations such as modifying or searching array elements. To call array methods, you use dot-notation on the array. For example: arrayVar.arrayMethod(func).

Array Methods accept a function as a parameter using the => operator. For example: arrayVar.arrayMethod( (functionParameters) => /* function code */ )

Looping Through Data with forEach()

To inspect each element in an array, we use the forEach() method, which runs a function on each array element.
