!important>inline style>id>class>pseudo elements>attribute selector>universal selector ....specificity order

[@spoiler3537]

Thanks

[@chinmoyborah186]

pseudo elements comes before classes.But in the case given in video, the pseudo element is applied to body and not h1(class header).So the colour will be blue. And pseudo elements like div:first-line comes even before div:first-child as the former applies directly to the first line, while the later is inherited from the element that it applies to.

[@chinmoyborah186]

A style that applies directly to the item takes precedence over inherited styles.

[@chinmoyborah186]

To stop the rerendering of child components while state in parent component gets updated , use React.memo on child component. useMemo is used for memoizing return values of functions or for memoizing any other values. An useCallback is used to memoize functions.

Thanks for explaining

answere of first quetion :
This is a heading
this how the perioty will for applying the CSS property
1. Element ID (#heading)
2. Pseudo classes (h1:first child)
3. Element tag nameh1 (h1)
4. Class name (“heading”)

[@vaibhavjaiswal1309]

no brother class have higher priority than tag name i guess

At 4:04, the output test and test2, as spread operator deep copies the primitive properties of the object( and for the nested objects it does shallow copying, which is the logic of the next question)

[@chinmoyborah186]

For duplicates, I prefer map()... Or sort the array and find unique elements in O(n) time complexity

[@ankushladani496]

Blue will the color
Concept is specificity
Classes and id's have more specificity.

[@ThereIsAnother]

the question at 1:00 is actually wrong lol.
It should be h1:first-child {} and not body:first-child{}. The second option won't even select the node we are looking for.
