In this lab, you will be working with JavaScript Higher Order Functions. A higher order function is a function that takes another function as an argument or returns a function. You will be working with the following higher order functions that are built into Javascript:
- Map
- Filter
- Reduce
Learning Objectives
Upon completion of this lab, you will be able to:
- Use the map method to iterate over an array and return a new array with the resulting values of the operation performed on each element.
- Use the filter method to iterate over an array and return an array with the resulting values that returned true based on the condition performed on each element.
- Use the reduce method to iterate over an array and return the resulting singular value due to the reducer function and the initial value provided.
Intended Audience
- Beginners learning front-end development
- Software Engineers who need to learn front-end technologies to expand their skillset
