how can I filter array in object?

I would like to filter only people who have the color red as favColor… how can I do that?
this is what i tried: but not worked

const filteredpersonen = personen.filter(personen => personen.favColor= 'red');
console.log(filteredpersonen);

This is my code:

let personen = [
    {
      naam : 'jan',
      age : 41,
      favColor:[
        'blue',
        'green',
        'yellow',
        'orange'
      ]
    },
    {
      naam : 'james',
      age : 31,
      favColor:[
        'red',
        'black',
        'yellow',
        'purple'
      ]
    },
    {
      naam : 'linda',
      age : 21,
      favColor:[
        'blue',
        'white',
        'red',
        'grey'
      ]
    },
    {
      naam : 'marya',
      age : 31,
      favColor:[
        'creme',
        'green',
        'orange',
        'red'
      ]
    }
  ]

>Solution :

1. = is assignment, == or === is comparison
2. favColor is an array, so doing favColor === 'red' doesn’t make sense

Use .includes

const filteredpersonen = personen.filter(personen => personen.favColor.includes('red'));
console.log(filteredpersonen);

let personen = [{
    naam: 'jan',
    age: 41,
    favColor: [
      'blue',
      'green',
      'yellow',
      'orange'
    ]
  },
  {
    naam: 'james',
    age: 31,
    favColor: [
      'red',
      'black',
      'yellow',
      'purple'
    ]
  },
  {
    naam: 'linda',
    age: 21,
    favColor: [
      'blue',
      'white',
      'red',
      'grey'
    ]
  },
  {
    naam: 'marya',
    age: 31,
    favColor: [
      'creme',
      'green',
      'orange',
      'red'
    ]
  }
]

const filteredpersonen = personen.filter(personen => personen.favColor.includes('red'));
console.log(filteredpersonen);
