How to check if all property values are true?

Question

var myData = {
  "value1": {
      "ext": false
  },
  "value2": {
      "ext": false
  }
};

myData.value1.ext = true;

How can I loop through myData to see if the ext for all the properties in my object are true?

Something like this:

if (value1.ext === true && value2.ext === true) {
     //do something
}

`if (Object.values(myData).every(v => v.ext)) { /* Yes, they're all true */ } else { /* No, they aren't */ }` — T.J. Crowder, May 23 '19 at 15:19

You can use every() on Object.values()

var myData = {
  "value1": {
      "ext": false
  },
  "value2": {
      "ext": false
  }
};


const res = Object.values(myData).every(x => x.ext);

console.log(res)

You could get the values and check the property.

var object = { value1: { ext: true }, value2: { ext: true } };

console.log(Object.values(object).every(({ ext }) => ext));

You can use every() to check if the values fit the condition:

var myData = {
  "value1": {
      "ext": false
  },
  "value2": {
      "ext": false
  }
};


const areValuesTrue = Object.keys(myData).every(value => myData[value].ext == true)

console.log(areValuesTrue)

You can do Object.values and then map to get all the value of ext. Then use includes to check if any true is there

var myData = {
  "value1": {
    "ext": false
  },
  "value2": {
    "ext": false
  }
};
let k = Object.values(myData).map(item => item.ext);
// this will be true if any ext value is true
console.log(k.includes(true))

Thanks. I would like to see if they are ALL true. – Si8 May 23 '19 at 15:23
@S` do you mean to set the value to true? – brk May 23 '19 at 15:23
I meant if the `ext` for `value1` and `value2` is `true` – Si8 May 23 '19 at 15:25
