#javascript #tutorial #beginners #testing

On this simple trick I'll show you how to compare objects more accurately using Object.is().

console.log(Object.is(0, '')); // => false
console.log(Object.is(null, undefined)); // => false
console.log(Object.is(undefined, undefined)); // => true
console.log(Object.is([1], true)); // => false
console.log(Object.is(NaN, NaN)); // => true

const obj1 = { name: 'Helder' };
const obj2 = { name: 'Helder' };
const referenceObj1 = obj1;

console.log(Object.is(obj1, obj2)); // => false
console.log(Object.is(obj1, obj1)); // => true
console.log(Object.is(referenceObj1, obj1)); // => true
