Can you explain what variadic functions are?
Sure! Variadic functions are functions that can accept a variable number of arguments. This allows for more flexible function calls.
How do you define a variadic function in JavaScript?
In JavaScript, you can define a variadic function using the rest parameter syntax. For example: function myFunc(...args) {}
.
Can you give me an example of using a variadic function?
Absolutely! Here's an example: function sum(...numbers) { return numbers.reduce((a, b) => a + b, 0); }
This function sums all the numbers passed to it.
Are there any downsides to using variadic functions?
Yes, one downside is that they can make the function's behavior less predictable, as the number of arguments can vary widely.
