[removed] convert two dimensional array to array of objects using the first 'row' to define properties

Question

In order to populate a data-grid that receives array of row objects, I am looking for a good solution to convert an array such as this:

[  
[\'country\', \'p         


        

Answer 1

Using a combination of map and forEach you can map the subsequent array elements to the columns specified in the first element.

var arr = [  
   ['country', 'population'],
   ['someplace', 100],
   ['otherplace', 200]
];

var cols = arr.shift();
newArr = arr.map(function(element,index){
   var newObj = {};
   element.forEach(function(data,index){
      newObj[cols[index]]=data;
   });
   return newObj;
});
