What are some common mistakes when using rest parameters in JavaScript?
An example of an AI chatbot conversation about common mistakes with rest parameters in JavaScript.
What are some common mistakes when using rest parameters in JavaScript?
One common mistake is trying to use rest parameters without the correct syntax. Remember, they should be the last parameter in a function.
Can you give me an example of the correct syntax?
Sure! Here's an example: function myFunction(...args) { console.log(args); } This correctly uses rest parameters.
What happens if I try to use rest parameters in the middle of the parameters?
If you place rest parameters in the middle, you'll get a syntax error. They must always be the last parameter.
Are there any performance issues with using rest parameters?
Generally, there are no significant performance issues, but using them excessively in tight loops can lead to overhead.
