Spread Operator vs Array Methods: Which to Use?

What is the difference between the spread operator and array methods in JavaScript?

The spread operator allows you to expand elements of an iterable, while array methods like map, filter, and reduce perform operations on arrays.

Can you give me an example of using the spread operator?

Sure! You can use the spread operator to combine two arrays like this: const combined = [...array1, ...array2];.

How does the spread operator compare to using the concat method?

The spread operator is more concise and often easier to read. For example, array1.concat(array2) vs const combined = [...array1, ...array2];.

When should I use array methods instead of the spread operator?

Use array methods when you need to transform or filter elements, as they provide more functionality than just combining arrays.
