f# - Does mkProgram expose more functionality than mkSimple? -


i trying understand difference between mksimple , mkprogram in fable-elmish, or elmish.wpf using. (can perhaps produce tag elmish.wpf please?)

i have found elmish.wpf incredibly effective, use in production, i'm @ stage i'm still learning lot every day. particular question gobbling of research time, appreciate help.

the comments in source looks this.

mksimple : simple program produces new state 'init' , 'update'.

mkprogram : typical program, new commands produced 'init' , 'update' along new state.

so commands for? have looked @ examples in several places, don't give of clue whether can same mksimple mkprogram, , that's need know.

does mkprogram expose functionality mksimple not, or can done whichever 1 use? mksimple simple demo use, , should using mkprogram real world applications grow? if can both, why difference?

mksimple learning purposes. helps ease new users framework not introducing ideas of cmd yet.

if @ source of mksimple, see doing hiding cmd idea (by using cmd.none) , calling mkprogram:

/// simple program produces new state `init` , `update`. let mksimple      (init : 'arg -> 'model)      (update : 'msg -> 'model -> 'model)     (view : 'model -> dispatch<'msg> -> 'view) =     { init = init >> fun state -> state,cmd.none       update = fun msg -> update msg >> fun state -> state,cmd.none       view = view       setstate = fun model -> view model >> ignore       subscribe = fun _ -> cmd.none       onerror = onerror }

its origins elm architecture, has since renamed simple program beginnerprogram.

if want want write program complexity, use mkprogram. if merely tinkering or demonstrating basics, may able use mksimple.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
