Can you explain the differences between rest and spread syntax in JavaScript?
Sure! Rest syntax allows you to collect multiple elements into an array, while spread syntax expands an array into individual elements.
Can you give me an example of rest syntax?
Of course! In a function, you can use rest syntax like this: function myFunc(...args) { console.log(args); }
This collects all arguments into an array called args
.
And what about spread syntax?
Spread syntax can be used to expand an array into individual elements. For example: const arr = [1, 2, 3]; const newArr = [...arr, 4, 5];
This results in newArr
being [1, 2, 3, 4, 5]
.
Thanks! So, can I use them in the same function?
Yes, you can! You can use rest syntax to gather parameters and spread syntax to pass them to another function or array.
