This video tutorial explains the REST and spread operators in JavaScript, both introduced in Ecmascript 6. The REST operator collects user-supplied values into an array, while the spread operator expands iterables into individual elements. The tutorial highlights the differences in their usage, particularly in functions, where REST is used to receive arguments and spread is used to send values. The video also provides examples of how these operators are applied in code.
