Join Carl Peaslee for an in-depth discussion in this video Function arguments, part of React: ES6, ES2016, and Beyond.
- [Instructor] In this video, we're going to be talking about…function arguments.…Function arguments combines some of…the functionality of the spread operator,…and also the object destructuring assignments.…Let's open up our examples directory,…and then we're going to take a look at the file here…called fuctionArgs.…I'll uncomment this.…Some of the new syntax in ES2016 allows you to use…the spread operator in the argument section of a function.…This allows you to access all of the arguments that are…passed into that function as an array.…
So here in function getEmAll, we see ...args,…and that means here when I console.log args,…I'd actually receive an array with each index representing…every single individual argument that's been passed…into getEmAll.…By specifying a default type in our argument,…that means we can avoid getting errors…if that specific argument is not passed into the function.…For instance here, on line seven, when I get some default,…I can use the equal sign in my argument to indicate…that I want my string to default to a string,…
