Why are loops faster in functions? This: a = [1:10_000_000;] b = zeros(Int64, length(a)) function double!(x, y) L = length(x) for i in 1:L @inbounds y[i] = 2x[i] end nothing end @time double!(a, b) is much faster than this: @time begin L = length(a) for i in…

For-loop in function is faster than global scope?
