    `[].find()` will help you – Sirko Jan 16 '20 at 05:28

You can use some() and test with in or Object.hasOwnProperty:

let arr = [ { "Apple": "fruit" }, { "Orange": "fruit" }, { "Cake": "sweet" } ] 

console.log(arr.some(obj => obj.hasOwnProperty('Apple')))
console.log(arr.some(obj => obj.hasOwnProperty('Bannana')))

This will return true for the first condition that matches and false if none match.
