Same here! I'm used to Python and just finished a Java crash course. Went straight here so I could learn all the different methods I could use.

Surely replacing the return function with just setting the result to the function name isn't best practice?

The only right answer :)

I'm pretty sure this is satirical

I mean that wasn't in the specification so not really necessary

I mean, you're not wrong

Wow, my fingers could never -

This site is meant for learning. By doing this, people learn new things like libraries

It looks clean, but making a variable called sum and mutating the input isn't best practice

I like how there's no 'else' here.

Mine isn't a one-liner and on average runs around 2800ms

better readability
