How can the spread operator facilitate the process of adding elements to state arrays in a React component without mutating the original state?
- Create a new array using the spread operator, add elements, and set the state
- Use the Array.push() method to add elements to the state array
- Directly modify the existing state array
- Utilize the Array.concat() method to add elements to the state array
The spread operator is used in React to avoid mutating the state directly. Creating a new array with the spread operator, adding elements, and then setting the state ensures immutability and proper state management in React components.
