Joining javascript key-value objects as string.

object_join.js

Object.prototype.join = function(glue, separator) { 
  var object = this;

  if (glue == undefined)
    glue = '=';

  if (separator == undefined)
    separator = ',';    

  return Object.keys(object).map(function (key, value) { return [key, value].join(glue); }).join(separator);
}

var options = { id : 1, name : 'lucas', country : 'brasil'};

options.join();
> "id=1,name=lucas,country=brasil"

options.join('=>', ' ');
> "id=>1 name=>lucas country=>brasil"

Object.keys(object).map((key) => [key, options[key]].join(glue)).join(separator)

Object.keys(object).map((key) => [key, options[key]].join(glue)).join(separator)

@alitoufighi, I was wondering where $ came from but your fix is very helpful and worked as expected. Thank U.

@cccabdalla the $ was a reference to the global jquery object, the original code is a bit old.

I will update it with the suggestion @alitoufighi sent, thanks.
