Hi freind. Thanks a lot for this great video. I want to know, what is the difference between keywords let and var

[mohtadibakali]

you can write a function like this function printProperty<T, K extends keyof T>(object: T, key: K) { let propertyValue = object[key] }

Hi Leela,

Thanks for the tutorial.

Small clarification,

We are looping person.hobbies (only the string array inside the object). But, inside the loop when I try to access person.name, I'm able to access the values.

for (let hobby of person.hobbies) {
console.log('hobby', hobby);
console.log('person', person.name);
}

It's an advantage or disadvantage?

Could you please clarify.

Thanks
