In this lab, you will be working with the JavaScript Rest Operator. The rest operator is a syntax with the purpose of capturing individual values and placing them into a data collection.
The rest operator is often used in conjunction with destructuring data collections.
The rest operator is sometimes referred to as the rest parameter. It can be used as a function parameter to capture excess values that are passed as arguments.
Learning Objectives
Upon completion of this lab, you will be able to:
- Use the rest operator to make a new object from the remaining object properties by using destructuring.
- Use the rest operator to destructure and create a new array from an existing array.
- Use the rest operator as a function parameter.
Intended Audience
- Beginners learning front-end development
- Software Engineers who need to learn front-end technologies to expand their skillset
