Compare two JSON objects in Angular

Question

I want to check if two JSON objects are same in Typescript(Angular), ignoring some key value pairs which may be optional.

obj1 = {name: 'Anna', password: 'test123', status: 'active'}
obj2 = {name: 'Anna', password: 'test123'}

Technically 'status' is optional, so I want the comparison to return true only considering first two properties. How to check this?

You could:

Get common keys of obj1 and obj2 (with a set)
Compare each key one-to-one

function compare(obj1, obj2) {
  const commonKeys = [...new Set([...Object.keys(obj1), ...Object.keys(obj2)])];

  for (const key of commonKeys) {
    if (obj1[key] !== obj2[key]) {
      return false;
    }
  }

  return true;
}

try this

 Boolean theSame= obj1.name==obj2.name && obj1.password==obj2.password;
