javascript - Cannot read undefiend of '.html' -


trying create new webserver using nodejs, got error saying .html undefined.

var mimetype = {     "html" : "text/html",     "jpeg" : "image/jpeg",     "jpg" : "image/jpeg",     "png" : "image/png",     "js" : "text/javascript",     "css" : "text/css" };  http.createserver(function(req,res){     var uri = url.parse(req.url).pathname;     var filename = path.join(process.cwd(),unescape(uri));     console.log('loading '+uri);      var stats;      try{         stats = fs.lstatsync(filename);     }catch(e){         res.writehead(404, {'content-type':'text/plain'});         res.write('404 not found\n');         res.end();         return;     }      // check if file/directory     if(stats.isfile){ //error happen here         var mimetype = mimetype[path.extname(filename)].split(".").reverse()[0];         res.writehead(200, {'content-type': mimetype});          var filestream = fs.createreadstream(filename);         filestream.pipe(res);     } }).listen(3000);

i'm new node, have no idea how debug. need , guidance.

the problem in these lines:

var mimetype = mimetype[path.extname(filename)].split(".").reverse()[0]; res.writehead(200, {'content-type': mimetype});

there, you're declaring mimetype variable in scope of createserver response handler function, making mimetype @ top of code inaccessible. so, mimetype undefined when try property it: mimetype[path.extname(filename)]

rename variable, , should work:

var contenttype = mimetype[path.extname(filename)].split(".").reverse()[0]; res.writehead(200, {'content-type': contenttype });

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
