Почему моя переменная не работает при принятии в качестве аргумента? ⇐ Javascript

[Anonymous]

Для человека, который пропускает его, я пытаюсь добавить год смерти, используя метод уменьшения для массива объектов. < /p>
Например: < /p>
{
name: "Carly",
yearOfBirth: 2018,
},
< /code>
{
name: 'Carly',
yearOfBirth: 2018,
yearOfDeath: 2025
}
< /code>
Why is using the passed variable causing the code to not function properly? I am new to this.
accum.push(passed = currentYear)
accum.push(person.yearOfDeath = currentYear)
See compared live examples with and without use of the variable.


const people = [
{
name: "Carly",
yearOfBirth: 2018,
},
{
name: "Ray",
yearOfBirth: 1962,
yearOfDeath: 2011,
},
{
name: "Jane",
yearOfBirth: 1912,
yearOfDeath: 1941,
},
]

const newArray = people.reduce((accum, person) => {
accum = []
accum.push(person)

let passed = person.yearOfDeath
const currentYear = new Date().getFullYear();
if (!passed) {
accum.push(passed = currentYear)

console.log(accum)
}
}, {})< /code>




const people = [
{
name: "Carly",
yearOfBirth: 2018,
},
{
name: "Ray",
yearOfBirth: 1962,
yearOfDeath: 2011,
},
{
name: "Jane",
yearOfBirth: 1912,
yearOfDeath: 1941,
},
]

const newArray = people.reduce((accum, person) => {
accum = []
accum.push(person)

const passed = person.yearOfDeath
const currentYear = new Date().getFullYear();
if (!passed) {
accum.push(person.yearOfDeath = currentYear)

console.log(accum)
}
}, {})< /code>
