Replacing a whole object within a specific array index with another object

I have the following javascript object:

const myValidation = [
   {
       id:'1', name:'qqq', field1: 'Yes', field2: 'No', field3: 'Yes'
   }, 
   {
       id:'330', name:'www', field1: 'Yes', field2: 'Yes'
   }, 
   {
       id:'45', name:'eee', field1: 'Yes' 
   }
]

Based on some condition within my code and if it's true, I want to replace myValidation[1] index object with the following object and it will always be at array index 1:

const newObj = {
           id:'331', name:'tom', field1: 'Yes', field2: 'Yes', field3: 'Yes', field4: 'Yes'
      }

So after replacing the object, myValidation array now looks like:

const myValidation = [
   {
       id:'1', name:'qqq', field1: 'Yes', field2: 'No', field3: 'Yes'
   }, 
   {
       id:'331', name:'tom', field1: 'Yes', field2: 'Yes', field3: 'Yes', field4: 'Yes'
   }, 
   {
       id:'45', name:'eee', field1: 'Yes' 
   }
]

Please note that I don't want to match on ids or any other key, I purely want to replace an object with another object at myValidation[1] index.

Unsure how to achieve this.

In your case it's very simple, just access the object in your array and set it to the object that you want.

myValidation[1] = { key:'value', key2:'value2'....}

If you ever get to a point where you need to do this without knowing it's the specifically the object in the array at index 1, you could use map and find to achieve this aswell.
