Why is arr = [] faster than arr = new Array?
...ould provide you a sufficient visualization so you can understand how much more (or less) processing is required.
Based on the above tokens, we know as a fact ARRAY_INIT will always produce an array. We therefore simply create an array and populate it. As far as ambiguity, the lexical analysis s...
Polymorphism vs Overriding vs Overloading

In an expression statement, the next sequence point is usually at the terminating semicolon, and the previous sequence point is at the end of the previous statement. An expression may also contain intermediate...
What is the good python3 equivalent for auto tuple unpacking in lambda?
...st not to say "there is no way out", a third way could be to implement one more level of lambda calling just to unfold the parameters - but that would be at once more inefficient and harder to read than your two suggestions:
min(points, key=lambda p: (lambda x,y: (x*x + y*y))(*p))

How does the new automatic reference counting mechanism work?
... great at. Humans forget things and make mistakes, but computers are much more consistent.
However, this doesn't completely free you from worrying about memory management on these platforms. I describe the primary issue to watch out for (retain cycles) in my answer here, which may require a littl...
