A modern programming language that makes developers happier.

as of now i see that Lambdas are better , they are more flexible because they are assigned to a variable which you can control and you don't need to write the word `return` to return something, the only draw back is _named arguments, which you cant do when calling a lambda but is there any thing that happens differently internally such as performance?_

I'm pretty sure, that on the JVM, lambda's will be (anonymous) functions internally.
So I don't think there's much performance difference between the two.
(Haven't tested performance difference, this is an assumption)

I would say, use whatever makes your code most readable.

Do you have a specific situation in which you're curious which to use?

In general, both have their strengths and weaknesses

no not really just in general, can you elaborate more on the strengths and weaknesses?

Honestly there are so many different possible situations that I don't know where to start with. Are you interested with call-site? Declaration-site? Are you a library author? Are you using local functions? How much do you care about performance? etc
