What’s the cleanest way to turn an object into a list without using a double for loop?



I have an object called ‘times’, that holds another object called ‘20102’, that holds a list of 3 objects. It looks like this:

times: {
    20102: [
        { name:'jane', age:12 },
        { name:'josh', age:19 },
        { name:'jill', age:14 },
    ]
}

However, what I want it to look like is this:

times:[
    { name:'jane', age:12 },
    { name:'josh', age:19 },
    { name:'jill', age:14},
]

I was thinking of doing a double for loop but that’s not efficient. What’s a better way?

Answer

using Object.values() and flat()

var x = {
  times: {
    20102: [{
        'key': '1'
      },
      {
        'key': '2'
      },
      {
        'key': '3'
      },
    ]
  }
};
x.times = Object.values(x.times).flat();

console.log(x);

If you know there will only be one key

var x = {
  times: {
    20102: [{
        'key': '1'
      },
      {
        'key': '2'
      },
      {
        'key': '3'
      },
    ]
  }
};
x.times = Object.values(x.times)[0];

console.log(x);
