JavaScript Reference vs Value Equality

equals.js

var personOne = {name: "Kyle", age: 22}
var personTwo = {name: "Kyle", age: 22}

// referential equality
let refEqual = personOne == personTwo

let isValueEqual = (obj1, obj2) => {
    return Object.keys(obj1).every(key => obj1[key] == obj2[key])
}

// value equality (deep equality)
let valEqual = isValueEqual(personOne, personTwo)

console.log({personOne})
console.log({personTwo})
console.log({refEqual})
console.log({valEqual})
