Why we reset the inheritance constructor?

[@kajalkashyap4068]

thanks for awesome video but ye smjh nhi aaya k constructor ko reset q krte h, bina reset kiye b work krta h...... please reply

[@sam-001]

Same problem

[@satyasahoo26]

Very helpful tutorial.

[@ajazamin9843]

sir here i think is a demerit
function extend (child,parent) {
child.prototype = Object.create(parent.prototype);
child.prototype.constructor = child;
} is fine, but when i try to add
child.prototype.anything = function () {
return(this.xyz);

}
and if i try to access this function through the object of its class it shows this function is not defined. why?

[@avkexpress8029]

owsm sir g very helpful to learn

[@sanjaygarg1146]

Sir please tell me why we are reset constructor ?

[@akshdesai3390]

because by default prototype object has 2 fields. one is constructor and second is prototype. but for this line "Lenovo.prototype = Object.create(Mobile.prototype);" we override the prototype object and now it has not second field called constructor. so that's why we need to reset the constructor. and need to put this line as well "Lenovo.prototype.constructor = Lenovo;"

[@wildturtle2416]

nice explanation

[@amolbonde6318]

Well described

[@user-gg5nh1mf6l]

You are great.
but how can I memorize those code? what should I do for that?

[@_samirdahal]

When you do big projects then you'll remember it automatically. Just practice, practice, practice.

Ye function h getModel() nam se yeha hum koi b namm rakh sakte h jaise ur name is anish to...getAnish()...etc

[@Raghav-Sharma]

You are too predictable now I guess your object name without seeing

[@geekyshows]

It will help to understand the concept easily. I also follow one pattern to explain various languages and frameworks so if A Person learns Django at Geekyshows He/She can easily grab other framework like Laravel at Geekyshows. I try to make them similar as much as possible.

[@Raghav-Sharma]

@@geekyshows yes I know that it's really convenient and easy to understand take this as complement thanks to your hard work I can easily understand the basics of the js
