iteration - Is there an implicit keyword in this Ruby Array map code? -

is there keyword can use explicitly tell map function result of particular iteration should be?

consider:

a = [1,2,3,4,5] a.map |element|   element.to_s end 

in above example element.to_s implicitly result of each iteration.

there situations don't want rely on using last executed line result, prefer explicitly result in code.

for example,

a = [1,2,3,4,5] a.map |element|   if some_condition     element.to_s   else     element.to_f   end end 

might easier me read if written like:

a = [1,2,3,4,5] a.map |element|   if some_condition     result_is element.to_s   else     result_is element.to_f   end end 

so there keyword can use in place of result_is?

return return calling function, , break stop iteration early, neither of i'm looking for.

yes, there is, it's called next. however, using next in particular case not improve readability. on contrary, a) confuse reader , b) give him impression author of code doesn't understand ruby.

the fact everything expression in ruby (there no statements) , every expression evaluates value of last sub-expression in expression fundamental ruby knowledge.

just return, next should used when want "return" middle of block. usually, use guard clause.
