---

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

constcomments= [
  { 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 }
];

constpeople와 constcomments에 대한 코드를 제공한다.

 

// Some and Every Checks
// Array.prototype.some() // is at least one person 19 or older?
const isAdult = people.some(person => ((new Date()).getFullYear()) - person.year >= 19);
console.log({isAdult});

// Array.prototype.every() // is everyone 19 or older?
const allAdults = people.every(person => ((new Date()).getFullYear()) - person.year >= 19);
console.log({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 comment = comments.find(comment => comment.id === 823423);
console.log(comment);

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

// comments.splice(index, 1);
const newComment = [
    ...comments.slice(0, index),
    ...comments.slice(index + 1)
];

주어진 소스를 활용해 주석에 있는 물음에 대해 답을 코드로 작성한다.
