Can you explain the difference between the spread operator and the rest operator in JavaScript?
Sure! The spread operator is used to expand elements of an iterable (like an array) into individual elements, while the rest operator collects multiple elements into a single array.
Can you give me an example of the spread operator?
Of course! For example, if you have an array let arr = [1, 2, 3];
, you can use the spread operator like this: let newArr = [...arr, 4, 5];
This results in newArr
being [1, 2, 3, 4, 5]
.
And what about the rest operator?
The rest operator is used in function parameters to gather remaining arguments into an array. For example, function myFunc(...args) { return args; }
will collect all arguments passed to myFunc
into the args
array.
So, can I use both operators in the same function?
Yes, you can! Just remember that the rest operator must be the last parameter in the function definition.
