Javascript treats this code in this order:
/*
var 1 is local to the particular scope because of var keyword
var2 and var3 will become globals because they've used without var keyword
*/
var var1; //only variable declarations will be hoisted.
var1= var2= va...

Remove a JSON attribute [duplicate]

@ggb667 you don't need to. Ordering doesn't matter for a JSON object. Without getting too deep in my explanation, it's like a Dictionary (or Map). Order matters if you are dealing with an array that contains objects or other values, since they don't ha...
Correct way to populate an Array with a Range in Ruby
... if the array is already created and you want to add a range to it: I have order = 1. Then order << (2.25).to_a. But this creates another array inside the array, I simply want the range from 2 to 25. Yet if I try order << (2.25) I get the error can't convert Range into Integer.

What is scope/named_scope in rails?
... scope :fresh, -> { where('age < ?', 25) }
scope :recent, -> { order(created_at: :desc) }
end
And you call
Zombie.rotting.fresh.recent.limit(3)
It translates to the below in SQL,
select "zombies.*" from "zombies" where "zombies"."rotting" = 't' and (age<20) order by create_at de...
Java 8 Distinct by property
...ream().filter(distinctByKey(Person::getName))
Note that if the stream is ordered and is run in parallel, this will preserve an arbitrary element from among the duplicates, instead of the first one, as distinct() does.

Position icons into circle

Rank items in an array using Python/NumPy, without sorting array twice
...
Use argsort twice, first to obtain the order of the array, then to obtain ranking:
array = numpy.array([4,2,7,1])
order = array.argsort()
ranks = order.argsort()
When dealing with 2D (or higher dimensional) arrays, be sure to pass an axis argument to argsort to...
