JavaScript A better way to create a heap of empty Objects

Simply use an object:

var objects = {};

for (let i = 0; i < 5; i++)
{
    objects["temp" + i] = {};
}

Accessing with:

objects["temp0"]

or:

objects.temp0

Or if you want to pollute the global namespace you can use:

for (let i = 0; i < 5; i++)
{
    window["temp" + i] = {};
}

And access using:

temp0
temp1 //etc.

or:

window["temp0"] //just like above
Answer:1
Array(5).fill({})
// [{},{},{},{},{}]

Array(5).fill("temp").map((x, i) => x + i)
// ["temp0", "temp1", "temp2", "temp3", "temp4"] 

Array.from({length: 5}, (_, i) => "temp" + i)
// ["temp0", "temp1", "temp2", "temp3", "temp4"]
Answer:2

It's like this:

function makeMadObjects(num){
  var a = [];
  for(var i=0; i<num; i++){
    a.push({});
  }
  return a;
}
var arrayOfObjects = makeMadObjects(27);
arrayOfObjects[4].someProperty = 'some value';
console.log(arrayOfObjects);
Answer:3
