Andrew gives an overview of arrow functions in Twig.
What is an arrow function?
Here’s an example of an arrow function (in generic code):
(value) => value * 5
This is what it would look like as a regular function:
function calc(value) {
return value * 5
}
As you can see, the arrow function version is a more succint way of writing the same thing. Notice that there’s no explicit return statement in the arrow function, like there is in the second example.
