What is the "prototype" linkage for Objects created via the Object Literal Notation in JavaScript? -


my first post on stack overflow , complete newbie here , still getting used rules / annotations followed on forum , please excuse aspiring "developer" ;-)

while reading through crockford's "good parts", came across line said:

every object linked prototype object can inherit properties. objects created object literals linked object.prototype, object comes standard javascript.

so test out wrote following jscript code:

var student = {} console.log(student.isprototypeof(object.prototype)) 

note:

  1. i executing via browser console , hence function - console.log(...).
  2. i guessing way student variable declared here using "object literal notation". isn't correct ?

so second line -

console.log(student.isprototypeof(object.prototype)) 

returned false instead of true. shouldn't display true instead of false ?

well doesn't contradict lines book mentioned above ?

so here snippet in action -

var student = {};  alert(student.isprototypeof(object.prototype));

i sure missing here sure!

the prototype of student (and other objects created via object initialiser) object.prototype.

i guessing way student variable declared here using "object literal notation". isn't correct ?

yes, that's 1 word it. spec calls object initialiser.*

so second line -

console.log(student.isprototypeof(object.prototype))

returned false instead of true. shouldn't display true instead of false ?

no, because student isn't prototype of object.prototype; it's other way around:

var student = {};  snippet.log(object.prototype.isprototypeof(student)); // true
<!-- script provides `snippet` object, see http://meta.stackexchange.com/a/242144/134069 -->  <script src="http://tjcrowder.github.io/simple-snippets-console/snippet.js"></script>


side note: overwhelming convention in javascript use mixed case initial capital letter constructor functions , objects used pseudo-namespaces. simple objects, , simple functions, start lower case letter convention (so, student rather student).


* "initialiser" "s", not "z", reason. eich american, either whoever wrote spec british or, ecma european organization — until 1994 european computer manufacturers association, after all — perhaps editor insisted on british rather american english spelling.
