Check if any key values are false in an object
You can use the Array.some
method:
var hasFalseKeys = Object.keys(ob).some(k => !ob[k]);
You can create an arrow function isAnyKeyValueFalse
, to reuse it in your application, using Object.keys() and Array.prototype.find().
Code:
const ob = {
stack: true,
overflow: true,
website: true
};
const isAnyKeyValueFalse = o => !!Object.keys(o).find(k => !o[k]);
console.log(isAnyKeyValueFalse(ob));
Here's how I would do that:
Object.values(ob).includes(false); // ECMAScript 7
// OR
Object.values(ob).indexOf(false) >= 0; // Before ECMAScript 7
