javascript - Trying to respond with text split into array of words from node.js http server -


new node.js, appreciate can offer. trying response out variable 'words' when start server , go localhost crashes , says " typeerror: first argument must string or buffer" when try write same variable console works. help!

var http = require("http"); var fs = require('fs'); var text = fs.readfilesync("text.txt").tostring(); var words = text.split(/\b/); function start(){ function onrequest(request, response){     response.writehead(200, {"content-type": "text/plain"});     var wordcounts = '';      for(var = 0; < words.length; i++)     wordcounts["_" + words[i]] = (wordcounts["_" + words[i]] || 0) + 1;         response.write(words);      response.end(); }  http.createserver(onrequest).listen(8888); console.log("server has started"); }  exports.start = start;

i'd this:

… var words = text.split(/\s+/); // hardly want split on every word boundary                                // rather on spaces in between …     var wordcounts = {}; // object, not string!     (var = 0; < words.length; i++)         wordcounts["_" + words[i]] = (wordcounts["_" + words[i]] || 0) + 1;     var result = object.keys(wordcounts).sort(function(a, b) {         return wordcounts[b]-wordcounts[a];     }).map(function(w) {         return w.slice(1)+": "+wordcounts[w];     }).join("\n");     response.write(result); // write string! …

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
