javascript - Which of these prototype declarations is better and why? -


this question has answer here:

i'm trying decide how set functions in prototype main library.

should use:

library.prototype.funca = function () {.....}; library.prototype.fucnb = function () {.....}; etc..

or 

library.prototype = {     funca: function () {.....},     funcb: function () {.....},     etc.. };

so first choice adds functions prototype. second option replaces prototype object containing functions. matter?

i go first option.

you don't want replace prototype, never know has been added project.

if it's self-contained working on, second ok option. still not habit don't inadvertently blow away functionality else counting on.
