Answer 8

Lambdas are basically just functions, that you don't name.
They should always return a value and are deleted after usage.

It's like saying
public static int foo (a, b, c) {
return a+b-c;
}
But you don't care about all the stuff you don't need there.
You just say
(a, b, c) => { return a+b-c;}

It is the same, but you spare all this unnecessary public static int foo

You could also use the function foo for a lambda replacement like so:
.filter(foo)
instead of
.filter((a) => { return (a == bar);})
But you can't use the lambda outside the function.
