내 코드

const people = [
      { name: 'Wes', year: 1988 },
      { name: 'Kait', year: 1986 },
      { name: 'Irv', year: 1970 },
      { name: 'Lux', year: 2015 }
    ];

const comments = [
     { text: 'Love this!', id: 523423 },
     { text: 'Super good', id: 823423 },
     { text: 'You are the best', id: 2039842 },
     { text: 'Ramen is my fav food ever', id: 123523 },
     { text: 'Nice Nice Nice!', id: 542328 }
   ];

// Some and Every Checks
// Array.prototype.some() // is at least one person 19 or older?
const date = new Date();
const isAdult = people.some(v => date.getFullYear() - v.year >= 19);
console.log("isAdults? ",isAdult);
    
// Array.prototype.every() // is everyone 19 or older?
const allAdults = people.every(v => date.getFullYear() - v.year >= 19);
console.log("is everyone 19 or older? ", allAdults);

// Array.prototype.find()
// Find is like filter, but instead returns just the one you are looking for
// find the comment with the ID of 823423
const id823423 = comments.find(v => v.id === 823423);
console.log("id823423: ", id823423);

// Array.prototype.findIndex()
// Find the comment with this ID
// delete the comment with the ID of 823423
const idx = comments.findIndex(v => v.id === 823423);
comments.splice(idx, 1);
console.log(comments);

쉬운 주제였고 제공된 코드랑 다를게 거의 없어서 내 코드만 올린당 🙃
