I want to pass in "he", and "she" to function func and output "heshe".
Is there any way to spread the value of object (like array) to make it work?
const func=(a,b)=>(a+b);
const arr=["he","she"];
console.log(func(...arr));//working
const obj1={a:"he", "b":"she"}
console.log(func(...obj1));//not working
You'll need to use Object.values().
In your example:
const func=(a,b)=>(a+b);
const obj1={a:"he", "b":"she"}
console.log(func(...Object.values(obj1)));
