noSql( list, query )

This function accepts a list of elements and an object known as the query. The method returns a list of all elements that have each of the key/value properties of the query.

Examples

  • var objects = [ { public : true, name : "Lion King" }, { public : true, name : 'Dumbo' }, { public : false, name : 'Lion King' }, { name : 'Xeon', rating : 5 } ];
  • noSql( objects, { public:true } )      should return this [ { public:true, name:'Lion King' }, { public:true, name:'Dumbo'}]
  • noSql( objects, { name:'Lion King' } )     should return this [ { public:true, name:'Lion King' }, { public:false, name:'Lion King'}]
  • noSql( objects, { rating:5 } )      should return this [ { name:'Xeon', rating:5 } ]
  • noSql( objects, { public:false, name:'Dumbo' } )  should return this [ ]
