Rest and Spread operators

In JavaScript, both spread and rest operators are represented by the ellipsis (three dots) syntax (...), but they have different meanings and use cases.
The spread operator is used to "spread" the elements of an iterable object (e.g., an array, a string, or an object with a Symbol.iterator method) into a new array or object literal. It is commonly used to combine arrays, clone arrays or objects, and pass arguments to functions.
The rest operator, on the other hand, is used to collect the remaining arguments of a function into an array. It is often used when the number of arguments passed to a function is not known in advance.
In summary, the spread operator is used to spread the elements of an iterable object, while the rest operator is used to collect the remaining arguments of a function into an array.
