Скачать или смотреть Spread and REST operators in Javascript

In this illustration:
The sum function uses the rest operator (...numbers) to accept any number of arguments and calculates their sum using reduce.
The spread operator (...) is used to combine arrays (arr1 and arr2) into a new array (combinedArray).
The spread operator is used for object spreading, merging the properties of person and details objects.
The rest operator is used in array destructuring to capture the first element and the rest of the elements.
The rest operator in object destructuring is used to capture the name property and collect the remaining properties in otherDetails.
These operators are powerful tools for handling variable numbers of arguments, combining arrays or objects, and more. They enhance the flexibility and readability of your JavaScript code.
