Converting array of objects into array for Google Charts

Question

I have an array of objects:

    [
      {
      SalePrice:"18000",
      TotalValue:"22500"
      ratio:1.25
      }
      {
      SalePrice:"128000",
      TotalValue:"212500"
      ratio:1.05
      }
    ]

and I want to form it into an array. like:

[
        [18000,  22500, 1.25],
        [128000,  212500, 1.05]
]

Using JS (ES6 is ok). I have tried using somelike like:

let array = data.map(({SalePrice, TotalValue, ratio}) => SalePrice, TotalValue, ratio).filter(s => s, t = >t, r => r);

but that doesn't work could anyone enlighten me please?

Answer 1

Maybe something like the following:

const data = [{SalePrice:"18000",TotalValue:"22500",ratio:1.25},{SalePrice: "128000",TotalValue:"212500",ratio:1.05}]
const mappedToArray = data.map(d => Array.from(Object.values(d)))
//[["18000", "22500", 1.25],["128000", "212500", 1.05]]

The advantage of this approach is not having to rely on hardcoded keys to access to properties in your object which the other answer does need. Which could also be a disadvantage in it's own if that includes properties Google Charts does not need.

Answer 2

let objectArray = ...;
let container = [];

objectArray.forEach(e => container.push([e.SalePrice, e.TotalValue, e.ratio]));
