javascript - Objects, prototypal inheritance, and a failing function -


this question has answer here:

while trying move on intermediate/advanced javascript concepts, i've run problem. in following code, object prototype , created objects seem functioning fine. when try use them in function 'winner', result declares winner second argument passed, regardless of score. here, mike has higher score(395) peter (206) , should declared winner. also, console logging message "peter wins score of function () { return (this.age * 5) + this.height; }".

any understanding i'm doing wrong appreciated.

var player = {      name: 'default',      age: 'default',      height: 'default',      score: function() {          return (this.age * 5) + this.height;      }  }        var mike = object.create(player);  mike.name = 'mike';  mike.age = 67;  mike.height = 60;      var peter = object.create(player);  peter.name = 'peter';  peter.age = 30;  peter.height = 56;      var winner = function(player1, player2) {      var player1score = player1.score;      var player2score = player2.score;            if(player1score > player2score) {          console.log(player1.name + ' wins score of ' + player1.score);      } else {          console.log(player2.name + ' wins score of ' + player2.score);      }  }    winner(mike, peter);  winner(peter, mike);

replace 

var player1score = player1.score; var player2score = player2.score;

with 

var player1score = player1.score(); var player2score = player2.score();

you have call function, if write player1.score body of function.

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
