Javascript Interview Questions ( Functions ) - Hoisting, Scope, Callback, Arrow Functions etc

var username='Addy negative';

var user={
rc1:()=>{
console.log('my name is '+this.username)
},
rc2(){
console.log('my name is '+this.username)
}
}

user.rc1(); // "my name is Addy negative"
user.rc2(); // "my name is undefined"

Why closure property is not working for rc2() ?????

@akshaymarch7 did it before it was cool! Huge respect for the man really. And kudos to guys like you who are helping us learn over top of what we learned from NamasteJs

You explain it so well , loved tNice tutorials tutorial.

The examples of callback function you gave are all called higher order function instead these functions accept callbacks as an argument.
Ya I can understand that sometimes they confused us lot don't worry , stay connected with us we all need your content we are liking this so much.

Thanks for sharing 👍

Very Nice Video !!
In last question, I guess one point is missing.
In arrow Function, hoisting doesn't work (It only works for regular function).

For example:
This will work:
console.log(addNum(5, 6))
function addNum(a, b) {
return a + b
}

But This one will not:
console.log(add(5, 6))
const add = (a, b) => {
return a + b
}

Please correct me.

Tell me the difference or why we need use function expression and iife

now i am in a good mood

Can you make series for MERN interview questions
