Object destructuring in a loop

How can I achieve this without hardcoding the index?

  const { TargetQuantity: targetQuantity1 } = res.data.d.results[0]
  const { TargetQuantity: targetQuantity2 } = res.data.d.results[1]
  const { TargetQuantity: targetQuantity3 } = res.data.d.results[2]
  const { TargetQuantity: targetQuantity4 } = res.data.d.results[3]

try this:

const results = [
  { TargetQuantity: 1 },
  { TargetQuantity: 2 },
  { TargetQuantity: 3 },
  { TargetQuantity: 4 }
];

results.map((item, i) => {

  let str ="TargetQuantity"+ (i+1) +" = item.TargetQuantity";
  eval(str)

});

This will create global variables TargetQuantity1,TargetQuantity2, TargetQuantity3 ... and so on

const results = [
  {TargetQuantity: 1},
  {TargetQuantity: 2},
  {TargetQuantity: 3},
  {TargetQuantity: 4}
];

(function (context){
  for(let i = 0; i < results.length; i++){
    context[`targetQuantity${i+1}`] = results[i].TargetQuantity;
  }
})(this);

console.log(targetQuantity3);

But why would you wanna do that?
