Answers for "check if object equals object javascript"

javascript check if objects are equal

const isEqual = (...objects) => objects.every(obj => JSON.stringify(obj) === JSON.stringify(objects[0]));

// Examples
isEqual({ foo: 'bar' }, { foo: 'bar' });    // true
isEqual({ foo: 'bar' }, { bar: 'foo' });    // false

javascript object equals

function isEqual(obj1, obj2) {
  const props1 = Object.getOwnPropertyNames(obj1);
  const props2 = Object.getOwnPropertyNames(obj2);
  if (props1.length != props2.length) {
      return false;
  }
  for (let i = 0; i < props1.length; i++) {
      let val1 = obj1[props1[i]];
      let val2 = obj2[props1[i]];
      let isObjects = isObject(val1) && isObject(val2);
      if (isObjects && !isEqual(val1, val2) || !isObjects && val1 !== val2) {
          return false;
      }
  }
  return true;
}
function isObject(object) {
  return object != null && typeof object === 'object';
}
