Hi,
I'd like to check which approach is a better one for the example below. The
task is rather simple, each string in vector "s" should be "surrounded" by
square brackets.
e.g.
s = AbstractString["as", "sdf", "qwer"] # s is typically a lot longer
@time st1 = AbstractString[ "[" * i * "]" for i in s ]
0.000057 seconds (16 allocations: 672 bytes)
3-element Array{AbstractString,1}:
"[as]"
"[sdf]"
"[qwer]"
@time st2 = map(x->"["*x*"]", s)
0.002932 seconds (33 allocations: 2.035 KB)
3-element Array{ASCIIString,1}:
"[as]"
"[sdf]"
"[qwer]"
The both expressions yield same results. I wonder whether from the language
design point of view one approach should be preferred over the other.
Comprehension here is considerably faster, I wonder why.
Thanks,
Jan
