      {
        name: "Kailash",

Answer 1

Using Array.map() and Array.find() can do it

let array1 = [
    {
      name: "Deepak",
      age: 20
    },
    {
      name: "John",
      age: 30
    }
    ]

let array2 = [
    {
      name: "Deepak",
      favGame: "Cricket"
    },
    {
      name: "John",
      favGame: "Football"
    },
    {
      name: "Kailash",
      favGame: "Basketball"
    }
   ]
   
let result = array2.map(a => {
   let obj = array1.find(i => i.name === a.name)
   if(obj){
    a.age = obj.age
   }
   return a
})
console.log(result)
