Spread / Rest operators in React JS | Learn ReactJS | CodeChef Learn Series
Welcome to Learn ReactJS for Frontend Development by CodeChef.
In this video, we explore the Spread (...) and Rest (...) operators in JavaScript and understand how they are commonly used in ReactJS applications. You’ll learn how the same three-dot syntax behaves differently based on context — either spreading values or collecting them — and why this distinction is essential for writing clean and maintainable React code.
This lesson covers:
Using the Spread operator to copy and merge arrays and objects
Passing array elements as function arguments
Using the Rest operator to handle variable function parameters
Common use cases of Spread and Rest in React development
This lesson is part of CodeChef’s Learn ReactJS for Frontend Development course and builds a strong foundation for modern JavaScript patterns used throughout React.
