es6 - cool example of use array destruction + advanced object literal to transform data

es6_transform_data_points.js

// from an array of arrays of points
const points = [
  [4,5],
  [10,1],
  [0,40]
];

// to array of objects x,y points
function transformPointsData(points){
  return points.map(([ x, y ]) => {
    return { x, y };
  });
}

console.log(transformPointsData(points));
/*
[
  { x : 4, y : 5 },
  { x : 10, y : 1 },
  { x : 0, y : 40 }
 ]
*/
