How to check object is present in JSON or not Using Javascript

Question

I have an array of the object users.

"users" : [
  {
     fname: "subrato",
     lname:"patnaik",
     password:"123"
  },
 {
     fname: "john",
     lname:"doe",
     password:"123"    
 }
]

I want to check whether the above JSON data contain the below object.

{fname:"subrato", password:"123"}

How could we do that in Javascript?

Answer 1

You're gonna need to loop through the array and do a check for it.

arr.forEach(obj => {
  if(obj.fname == 'name' && obj.password == 'password') {
    // Do stuff
  }
})
