Little regexp magic to parse params

paramparser.js

var text = 'Little brown="and yellow" fox=1 jumps over=lazy dog';

var res = text.match(/([^=\s]+="[^"]+")|\S+/g).map(function (p) {
    return p.match(/^([^=\s]*)(?:="?([^"]*)"?)?$/).splice(1, 2);
})  

console.log(res);

// Output

res =
[ [ 'Little', undefined ],
  [ 'brown', 'and yellow' ],
  [ 'fox', '1' ],
  [ 'jumps', undefined ],
  [ 'over', 'lazy' ],
  [ 'dog', undefined ] ]
  
// If you are going to use the code, I suggest using underscores map function to handle null results easier:

var _ = require('underscore');
var res = _.map(text.match(/([^=\s]+="[^"]+")|\S+/g), function (p) {
    return p.match(/^([^=\s]*)(?:="?([^"]*)"?)?$/).splice(1, 2);
})
