The new operator lets developers create an instance of a user-defined object type or of one of the built-in object types that has a constructor function. In this two part video series we will look how new operator works, what all different use-cases can arise, and some good to know around this operator.

This video topic is quit basic but most of the experience person also don't know. Thanks for taking efforts on these kind of video. Expecting more such videos. Very informative and clean explanation. Thanks.

Loved it, especially how you explained everything from the ground up, making it both beginner and intermediate friendly

TIL that returning a primitive value from a constructor function returns the implicit this. Thanks for the explanation.
Just a follow up, if we'd want to make sure that the constructor function is invoked using the "new" keyword, we could also use `if(!(this instanceof ConstructorFunction)){throw new Error("Call me with new keyword")}` right? I was wondering what's the difference between using `new.target` and `instanceof`?
