The copywithin method is a powerful but sometimes overlooked JavaScript array method that allows you to copy a section of an array to another position within the same array, without modifying its length.
Syntax:
javascript
Copy
Edit
array.copyWithin(target, start, end)
target: The index where the copied elements will be placed.
start: The index at which copying begins.
end (optional): The index at which copying stops (not included).
Example Usage:
javascript
Copy
Edit
let numbers = [1, 2, 3, 4, 5];
numbers.copyWithin(0, 3, 5);
console.log(numbers); // Output: [4, 5, 3, 4, 5]
Key Points to Remember:
The method mutates the original array.
The elements are copied, not moved.
The end parameter is optional and non-inclusive
