i trying figure out equivalent of java in clojure: public int compute(int x) { if (x < 0) return 0; // continue computing return result; } is there idiomatic clojure "break" processing within function , return result? no. there no short-circuit return statement (or break or goto ... ). return implicit. a near equivalent in clojure example is (defn test [x] (if (< x 0) 0 (let [result (comment compute result)] result))) but return result without naming it: (defn test [x] (if (< x 0) 0 (comment compute result))) these run, comment evaluates nil . by way, if construct 2 expressions (rather full three) returns nil if test fails. (if (< 3 0) 0) ; nil so there return.

update : i've found solution slighty same in first answer. but in fact i'd know if there manner using requirejs, without using special var or parameters in views . here solution : define(['resthub', 'backbone', 'views/mymodule/parent-view', 'views/mymodule/a-view'], function(resthub, backbone, parentview, aview) { var parentview = backbone.view.extend({ // stuff before buildaview : function(aviewobject){ var aview = aviewobject || aview; // enought source code before , after following lines // don't want duplicate in childview this.aview = new aview(); this.aview.render(); } // stuff after }); return parentview; }); i try use maximum inheritance in backbone project dependencies managed requirejs avoid duplicate code. in fact, create new view extend base view. base view has dependency want override. if try override, origina...
