'use strict';

let objArray = [
     { id:0, name:'Jonah',   otherProp:321 },
     { id:1, name:'Andrew',  otherProp:648 },
     { id:2, name:'Another', otherProp:850 },
     { id:3, name:'Quite',   otherProp:146 },
     { id:3, name:'Not quite', otherProp:9 },
     { id:4, name:'Mary',    otherProp:984 }
];

let findName = (idNr) => {
   let test = (obj) => obj.id === idNr;
   let ob = objArray.find(test);
   return (ob !== undefined) ? ob.name : 'Not found';
};

document.write(findName(3) + '<br>');
document.write(findName(5) + '<br>');
