The purpose of function is to get false when all answers are empty. Currently, some how getting **false when only one single answers empty and rest have data inside.
what is the best way to check all answers are empty or not. It doesn't matter some has data and some doesn't. I just wanna see all empty or not.
const questions = [{
"answers": [{
"value": "Browns",
"selected": false,
},
{
"value": "Oranges",
"selected": false,
},
{
"value": "Purples",
"selected": false,
}
],
"info": "",
"type": "DESELECT",
"lastUpdated": "2021-11-01T22:50:28.359"
},
{
"answers": [],
"info": "",
"type": "DESELECT",
"lastUpdated": "2021-11-01T22:50:35.392"
},
{
"answers": [{
"value": "AnimalPrints",
"selected": false,
},
{
"value": "BigLogos",
"selected": true,
},
{
"value": "Floral",
"selected": false,
}
],
"info": "",
"type": "DESELECT",
"lastUpdated": "2021-11-01T22:50:43.883"
}
];
console.clear();
console.log("------------ES6------------");
const es6Result = questions.every((item) => !_.isEmpty(item.answers));
console.log(es6Result);
const lodashResult = _.every(questions, !_.isEmpty('answers'));
console.log("------------Lodash------------");
console.log(lodashResult);<script src="https://cdn.jsdelivr.net/npm/lodash@4.17.21/lodash.min.js"></script>You could use .some(), you will get true if at least 1 answers is not empty, and you will get false if all answers are empty
const es6Result = questions.some((item) => item.answers.length);
I think the logic you describe requires:
const lodashResult = !_.every(questions, _.isEmpty('answers'));
or
const es6Result = !questions.every((item) => _.isEmpty(item.answers));

const es6Result = questions.map((item) => _.isEmpty(item.answers)).indexOf(true) > -1;
console.log(es6Result);<script src="https://cdn.jsdelivr.net/npm/lodash@4.17.21/lodash.min.js"></script>
