If u don't mind u hve any specific definition for window ?
It's a inbuilt object provided by browser

Just try with your doubt then you can easily understand
05:00 create a window object and acess through window object ( window object act like a pareent)
👍
13:40 lo object key :value pairs

th-cam.com/video/fD1Fyfm8TZc/w-d-xo.html
th-cam.com/video/VbSJJsb6dLE/w-d-xo.html
this keyword works based on its scope?
i am right?
Not exactly scope
@@csworldtelugu ok mam now i watched complete videos of this
Thankyou , Good explanation
@@jalandharbandari4092 good
ma'am if we let it shows undefined why?
I didn't
Let and const variables are block-scoped, which means they only exist within the block only... The window object doesn't have access variables which are declared with let and const keywords. Then it shows undefined
akka please koddiga dark mode use cheyyava
Sure I will use
@@csworldtelugu thanks akka
Promises,asnychronous js
I will explain next week
1)00:00 explain about different types of this method.
2)01:49 this key word in console.log method based on place where i used this keyword we get values.value of this key word outside of function and object.
3)09:50 create a this key word inside function
4)11:05 this keyword inside method.
5)14:30 this keyword inside event handler.
6)20:15 strict mode
Thanks
04:20 note point this always indicate the objects between curly brases
05:56 it is belong to window object are not can we check
08:00 if we use this as directly with one name this.x that is belong to the the window object idhi dudi gurthu
10:35 this will give window object as result for both inside and outside the function
,"Embroiderad"
Thanks
code snippet
//note in javascript everty thing is object
//we used this in different places base on point of location it will give output
// console.log(this)
// var x="jegini"
// this keyword outside a object
// console.log(this)
// test= {
// x:"jegini lokesh"
// }
// function add(a,b) {
// sum=a+b;
// }
//this act like a global object if we use outside a function.
// console.log(x);
// console.log(window.x);
// console.log(this.x);
// console.log(this.test)
//this is used inside the function.
// function inside( ) {
// console.log(this.x)
// }
// inside()
movie={
name:"rrr",
hero:"ntr",
title:function() {
console.log(this)
}
}
console.log(movie.title())
//event listine method
window.onload = function() {
var d=document.getElementById('loki3');
d.addEventListener('click',face)
}
function face() {
console.log("this is from event listiner",this)
}
//use strit is pending
Good
