How do I merge arrays using the spread operator in JavaScript?

How do I merge arrays using the spread operator in JavaScript?

You can merge arrays using the spread operator by placing the arrays inside square brackets. For example: const merged = [...array1, ...array2];.

Can you give me a practical example?

Sure! If you have const array1 = [1, 2, 3]; and const array2 = [4, 5, 6];, you can merge them like this: const merged = [...array1, ...array2]; // merged will be [1, 2, 3, 4, 5, 6].

What if I want to add more arrays?

You can simply add more arrays in the same way: const merged = [...array1, ...array2, ...array3];.

Is there a limit to how many arrays I can merge?

No, there's no specific limit to the number of arrays you can merge using the spread operator, but keep performance in mind with very large arrays.
