Check For A Object Key Inside In Multiple Arrays [JavaScript]

Hi I am trying to find the best way to check whether an object key is present inside multiple objects present in an array which will provide a boolean as output
[{alert:hi},{alert:bye},{}]

from the above example basically what I am trying to achieve is if any one object is missing the alert object key the output should be as false or anything

>Solution :

You can iterate your array with every(). Something like this:

const objects = [{alert:'hi'},{alert:'bye'},{}];
const every = objects.every(obj => obj.hasOwnProperty('alert'));
console.log(every);
