Map an the values from an array of objects to another array of arrays to match a new data structure

Question

How do I get the requiredObject data structure from the rows and columns variable? I know I need to use some higher-order array methods like map, etc. I just find the right combination

Posting image for code is bad practice. Is it to avoid some teacher finding his given homework online ? — kriss

This is what I use currently, I am sure there's a better looking solution

let colArray = columns.columns.map(col => col.name)

let transfromedData = []
rows.forEach(row => {
  let temp = {};
  colArray.forEach((key, i) => {
      temp[key] = row[i];
    })
    transfromedData.push(temp)
})

  const sortedColums = columns.columns.sort((a,b) => a.value - b.value).map(x=>x.name)
  const output = rows.map(x => { const entry = {}; x.map((val, idx) => entry[sortedColums[idx]] = val); return entry})
