I think event bubbling definition you gave is wrong. Event bubbling is a way of event propagation in the HTML DOM API. Suppose there is a element with a child element and both have registered a event listener for same thing. So with bubbling, when the event is fired, it is handled by the innermost element and then propagated to outer elements.

React js is a shame to JavaScript community. Governments should ban the use of this stupid library. Same functionalities can be achieved with Angular and Svelte with less frustration, so what's the point of using the stupid react js which makes web development unnecessarily complicated.?

No one asks questions on unit testing the code which is perhaps one of the most important things a developer can do to ensure quality. Also what is the purpose of asking someone what a box model is? A front end developer doesn't have to know what a combination of content, margin, border is called if he knows what they are and how to use them properly. These guys ask ridiculous questions to devs.

@sweshmishra123 Жыл бұрын

Asking about box model is totally valid, which CSS properties are part of box model and which are not, this will help you making a scalable htm design.

@phoneix24886 Жыл бұрын

@@sweshmishra123 A developer does not have to know the term "Box model" to do that. Like the interviewee explained. he could not recollect the exact theoretical term at first but he remembered it had to do with the margin, padding and content. The point is asking such theoretical questions to an experienced candidate makes 0 sense. It does not represent a good judgement of the actual skill that the dev possess and often lead to bad hiring.

@sweshmishra123 Жыл бұрын

Box model is not just a theoretical concept, it has a practical implementation Consider a problemtic use case , Let's say element1 on hover of element1 you want to show border around this element1 and suppose there are some other elements also present alongside on the same axis . Here in hover state CSS of element1 you must not use border property it will cause a flickering effect. Because borderwidth will add up to the total width of element1 and on mouseout the width of element1 will decrease. The person who is having knowledge of box model would be able to fix this problem. You must know which CSS properties are part of box model and which are not..

Closure u explained was completely wrong, u just explained about nested function it’s not closure. By the way video was very helpful..thank you

@sarojdash7210 2 жыл бұрын

well he is not completely wrong. A closure is the combination of a function bundled together (enclosed) with references to its surrounding state (the lexical environment). In other words, a closure gives you access to an outer function's scope from an inner function. In JavaScript, closures are created every time a function is created, at function creation time. src:MDN

@chaitram4141 2 жыл бұрын

@@sarojdash7210 well , ur definition to closure is 100% right , however practical example which he took in video is wrong , its not closure ..he should have used return statement to the inner function then closure concept come into picture because when we return the function, the parent func completely move out from the call stack (Execution context) but the inner function still have the access to lexical scope of its parent its called closure Eg : function count(){ let counter = 0; return function(){ counter++; console.log(counter); } } let getCount = count(); getCount();

@sarojdash7210 2 жыл бұрын

@@chaitram4141 You are also correct with your example brother. even your example is a better one. but that example is still valid. function Parent() { let count = 0; function child() { count += 1; debugger; console.log('count value is '+count) } child(); } Parent(); you can run it as snippet in chrome or add a script to a html and give reference. while running the file you will notice under source tab right panel there is scope and under scope you will find closure key and value.
