What are the best practices for using spread parameters in JavaScript?
Using spread parameters can simplify function arguments. It's best to use them when you expect a variable number of arguments.
Can you give me an example of how to use spread parameters?
Sure! You can define a function like this: function sum(...numbers) { return numbers.reduce((a, b) => a + b, 0); }
.
Are there any performance considerations I should be aware of?
Yes, while spread parameters are convenient, they can lead to performance issues if used excessively in tight loops.
What about using spread parameters with arrays?
You can easily merge arrays using spread parameters, like this: const combined = [...array1, ...array2];
