I have object contain these data

{
    'c':'d',
    'd':'a',
    'e':'f',
}

I am trying to use the array find() like this

let found = Object.entries(myobject).find(item => item['d'] == 'a');

but I get undefined for found value so how I should write this ?

Object.entries() returns array of pairs, where the first element of each pair is key, and the second element is value. So the callback in .find() will receive pair as argument, and then you can check its key (pair[0]) and value (pair[1]):

const myObject = {
  'c': 'd',
  'd': 'a',
  'e': 'f',
}

const found = Object.entries(myObject)
  .find(pair => pair[0] === 'd' && pair[1] === 'a');

console.log(found);

Alternatively, you can use array destructuring in function parameter:

const myObject = {
  'c': 'd',
  'd': 'a',
  'e': 'f',
}

const found = Object.entries(myObject)
  .find(([key, value]) => key === 'd' && value === 'a');

console.log(found);
