someone can help me to create a predicate function into the method findKey() of (_) object .so that function looks through a value property to find word have “w” character that’s her code :








const _ = {
  
findKey (object, predicate) {
 for (let property in object) {
   let prop = object[property]
function predicate (prop) {
  for(let property in object) {
  for(let i = 0; i < prop.length; i++) {
 if(prop[i] == "w")
 return property   
  }
 return "undefined"
}
 }
  
}
}
}
console.log(_.findKey({'name': 'pedro', 'surname': "pedrossa", 'adress' :"kairwan"}))
module.exports = _;
