js compare objects

const isEqual = (...objects) =>
  objects.every((obj) => JSON.stringify(obj) === JSON.stringify(objects[0]));
if (!isEqual(this.lastValue, val)) {

js compare tow object values

//turn them into text then compare their values
JSON.stringify(obj1) === JSON.stringify(obj2) 
/*not the best solution but work for simple objects without methods 
Happy Coding */ (●'◡'●)
